Traditionally its the waitstaff and bartenders who earn tips from serving the food. It is however the chef that does most of the work by actually preparing the food. Do you think the cook should be tipped?
Lol when I first read your question, I thought you meant a tip like "stand back or you'll burn your eyebrows!"
Ummm money tips.... well I don't like tipping waiters as I would rather they were just paid a decent wage to start off with. One of the reasons I liked living in Brussels was that tipping was frowned upon, the waiters were paid properly and service (and food!) was uniformly excellent.
If I'm in a country where tipping is required then I do alter how much a tip depending on the quality of service. I've never tipped a chef but I have sent congratulations back to the kitchen. One of the problems I guess is that there can be many chefs in one kitchen, all working on different aspects of your meal - how would you tip them all?
Yes they should be given tips and compliments, every bit as generously as they are criticised.
Even in tiny restaurants or cafes, food cooked and presented well, should be acknowledged and complimented. And rewarded.
Don't believe in tipping whatsoever, particularly in Australia, where salary is good. So's the OT. Base line, they're just doing their chosen job, for which they're being well paid; they're NOT doing it for free!
What's with this tipping of Restaurant employees' anyway? Do you tip the bus driver, the butcher, your GP? No, of course not, so again, WHY Restaurant staff?
