First day on Saturday! (UK)

I'm not sure if this is the right flair but after months of looking for my first job, I've been accepted at McDonald's! Got my uniform yesterday and my first shift is this Saturday. I'm really nervous but also sort of excited as friends who work at different McDonald's in the area have told me good things about working here.

If anyone has any advice for me, that'd be greatly appreciated, and I'm really happy to be part of the team!
