You're excited for Wimbledon but all those stewards in fancy uniforms are slightly worrying.
It's okay, we've all been there.
Wimbledon is one of the most prestigious tennis tournaments in the world, and one of the highlights of the British summer, so we've put together a list of etiquette recommendations to make sure you get the most out of the tournament.
1. Leave the selfie stick at home.
They're banned at Wimbledon.
2. Don't leave your seat...
...in the middle of play. You can leave your seat only at specific times: after the 3rd game at the start of a set, every 2 games thereafter, and at the end of a set. Don't worry about keeping track though - there will be a noticeable pause and the Wimbledon stewards will start herding people on and off the court. But if you do stand up to move outside of those times, you might get a stern word from the umpire.
Don't make noises during rallies. Tennis players need concentration, and it makes the cheers when your player has won even sweeter.
4. It's Murray Mound not Henman Hill.
Okay so there's a lot of dispute over this one, but if Murray's playing the day you go to Wimbledon then it's definitely Murray Mound.
5. Don't be rude when a player is serving.
It's always fun to shout 'come on Andy!,' and we all want to be the last person to scream it so we know he hears. However, the players and the umpire start to get annoyed if the cheering goes on too long. Make sure you don't make a sound when the player has actually started to serve - it's the most important part of a point!
6. Take food and drink.
There is food and drink available within the grounds, but it can be expensive and there will be long queues. If you pack food and drink then you won't feel like you have to leave your great Court 3 seats because you're feeling hungry, so crack out a sandwich between sets and enjoy all the tennis you can! Be aware, though - if you're bringing your own booze you're limited to one bottle of wine or two cans of beer.
7. Be careful with your claps.
It's considered rude to applaud a double fault, and the loudest cheers will always go to the points where a player has played particularly skilfully, rather than when they've won the point as a result of their opponent's mistake.
8. Enjoy yourself!
