Tips and advice on Bar/Waitress role please!

[LifesTooShortYOLO]

So I've just been offered an ideal flexible job that fits with school hours and I'm so excited!
It's waitress/bar service and although I've waitressed before 10+ years ago I never did the bar.
So what's your best advice and tips for pulling a decent pint?!
Anything I should know?
Any help or tips greatly appreciated 😊
Thanks

Based on my experience *

The best bar staff are very aware of who is next in the queue to be served.

Your job is to be as quick and efficient and friendly as possible

Familiarise yourself with where everything is so you can be as efficient as possible

Don't be afraid of asking people to repeat the order if it's a big one
