Two Brighton men have been in the news today, after being banned for life from a local all-you-can-eat Mongolian restaurant. Apparently the restaurant owner had underestimated just how much it was possible for a person to eat, and was worried for his livelihood.
And they are not the first to find themselves out in the cold.
The two men, 26-year-old former rugby player George Dalmon, and his friend Andy Miles, had been regulars at the Gobi Mongolian restaurant in Brighton. They paid £12 a time, drank only water, and would regularly put away five or more bowls of stir fry.
The manager told reporters: "Basically they just come in and pig out. We have put up with them for two years but I've had enough."
The manager pointed out that as a business he has the right to serve who he likes: the men argued that all-you-can-eat should mean nothing more or less.
But while it can't have been a pleasant experience for the business or the diners, they can take comfort from the fact that there are plenty of others in the same position.
This summer, British heavyweight boxing champion David Price suffered the same indignity - thrown out of a buffet for eating too much. In his case, the 6'9", 18 stone, 29-year-old sportsman paid £14.95 at a Chinese restaurant, and consumed so much food he was asked to leave.
In this case, he said he wasn't surprised his appetite had alarmed staff, as a fried breakfast alone for him will include six sausages, seven rashers of bacon, four fried eggs, black puddings, beans, mushrooms and seven or eight pieces of toast.
Meanwhile, across the pond, 350lb 6'6" Wisconsin man Bill Witsh hit headlines after being thrown out of a fried fish buffet for consuming too much. Staff gave him a doggy bag, but even this wasn't enough to stop him picketing the restaurant.
Is this fair?
The question of who is in the right is somewhat vexed. If somewhere advertises that you can eat what you want, they don't tend to put 'within reason' in the small print, so you could feel irritated if you are left hungry.
On the other hand, these are businesses that need to make money in order to keep going. In order to profit from this sort of deal they need to calculate the average amount a person tends to eat, and price the buffet accordingly. If they get a few outliers who can consume their bodyweight in food, they can either put the price up to reflect that - or they can throw them out.
It makes sense for the business and the majority of their customers to keep a lid on the maximum that can be eaten, so they can avoid putting prices up.

10 of the biggest consumer rip-offs
Banned from all-you-can-eat for over-eating
Using a mobile phone to make and receive calls, send texts and browse the web while abroad can be extremely costly – especially if you are travelling outside the European Union (EU), where calls can cost up to 10 times as much as at home.
To avoid high charges, Carphone Warehouse suggests tourists ensure a data cap is in place, use applications to check data usage, turn off 'data roaming', avoid data-intensive applications such as Google Maps and YouTube and use wi-fi spots to update social networking sites.
Payment Protection Insurance (PPI) is supposed to help people to continue meeting their loan, mortgage or credit card repayments if they fall ill or lose their jobs. However, policies are often over-priced, riddled with exclusions and sold to people who could not make a claim if they needed to.
At one point, sale of this cover - which was often included automatically in loan repayments - was estimated to boost the banks' profits by up to £5 billion a year.
Now, though, consumers who were mis-sold PPI can fight back by complaining to the bank or lender concerned and taking their case to the Financial Ombudsman Service (08000 234567) should the response prove unsatisfactory.
It could be you, but let's face it, it probably won't be. In fact, buying a ticket for the Lotto only gives you a 1 in 13.9 million chance of winning the jackpot.
With odds like that, you would almost certainly be better off hanging on to your cash and saving it in a high-interest account.
No-frills airlines such as EasyJet may promote rock-bottom prices on their websites. But the overall fare you pay can be surprisingly high once extras such as luggage and credit card payment fees have been added - a process known as drip pricing.
Taking one piece of hold baggage on a return EasyJet flight, for example, adds close to £20 to the cost of your flight, while paying by credit card increases the price by a further £10.
It may therefore be worth comparing the total cost with that of a flight with a standard airline such as British Airways.
Cash advances, which include cash withdrawals, are generally charged at a much higher rate of interest than standard purchases.
While the average credit card interest rate is around 17%, a typical cash withdrawal of £500, for example, is charged at more than 26%.
What's more, as the interest accrues from the date of the transaction, rather than the next payment date, costs will mount up even if you clear your balance in full with your next payment.
Supermarkets such as Tesco and Asda often run promotions under which you can, for example, get three products for the price of two.
However, it is only worth taking advantage of these deals if you will actually use the products. Otherwise, you are simply buying for the sake of it, which is a waste of your hard-earned cash.
Buy a train ticket at the station on the day of travel and the price is likely to give you a shock - especially if you are travelling a long distance at a busy time of day.
However, you can cut the cost of train travel by 50% or more by going online and making the purchase beforehand - especially if you book 12 weeks in advance, which is when the cheapest tickets are on sale.
Other ways to reduce the price you pay include avoiding peak times and taking advantage of so-called carnet tickets, which allow you to buy, for example, 12 journeys for the price of 10.
Most High Street banks offer packaged accounts that come with monthly fees ranging from £6.50 up to as much as £40, with a typical account charging about £15 per month.
Various benefits, such as travel insurance and mobile phone insurance, are offered in return for this fee. But whether or not it is worth paying for them depends on your individual circumstances.
