Things i've learnt in my year as a waitress!

Thought id enlighten you all into my life a little bit, I have been working part time (alongside sixth form) as a waitress for about a year and 3 months. In this time I have come accross some essential information you just must know to do this job.

1) The boss is always right.
2) The chefs are always right.
3) The customer is always right.
4) You are never right.
