I actually agree with Will; I work in the same kind of place and I work my arse off trying to get the best service, and all we get back is s**t, I mean for example today someone threw their food at me becuase we where still waiting for 'x' product to be cooked, so I offered him a double of 'x' and he threw it at me. Once you've worked in a customer based environment, I can guarentee you that when you go into a shop or restaurant you will treat them with some respect. Just say please and thank you, it really isn't that f**king hard!
