Six people were refused entry to a Vaccines gig at Venue Cymru in Llandudno, Wales - after they couldn't name the lead singer. Security guards turned quiz-masters for the evening, after a tip-off that the event was being targeted by pickpockets.
So did it work? And was it fair?
According to The Daily Post, the security guards asked concert-goers to name the band before the gig on Monday. Then they asked them to name the lead singer (Justin Young), and the band's albums (What Did You Expect From The Vaccines? and Come Of Age).
Some of those who couldn't name the singer or the albums were refused entry. In all, six people were turned away and had their £18.50 tickets confiscated. Two more were asked to leave after gaining entry.
Is it fair?
On the one hand, it could be deemed a success. The move was designed to weed out the pickpockets, and there were no reported thefts on the evening and no-one was arrested.
Gangs of pickpockets targeting mobile phones has become a real threat for concert-goers, because they can strike easily among a distracted crowd. Phones are not just taken out of pockets, but from zipped bags, and even snatched from people who are taking photographs. Some gangs will target specific venues, while others will follow a tour, striking at every gig.
Fans of the Vaccines are considered a good target because there's close contact in the crowd, especially at the front of the stage. They have been targeted on this tour already: at a show last week in Bridlington 20 smartphones were taken.
On the other hand, there were some real fans refused entry after a momentary memory lapse. Andy Bellis from Wrexham, a singer in a local band, told the Daily Mail that he felt under pressure and couldn't remember the details. He was refused entry.
Venue manager Sarah Ecob told the Mail that they had taken the step after receiving information that pickpockets were preparing to target the event. She apologised to Bellis and any other true fans refused entry, and confirmed that tickets would be refunded.
10 of the biggest consumer rip-offs

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.
