I have a tip jar in my pizza shop that I run, however it is not because we expect tips it is because for some God unknown reason quite a few people tip us when they pick up their food and we need somewhere to put it so we can split it at the end of the night. I do not understand why people tip me when they pick up their food but hey thats on them. Now when I deliver I do get a little pissed off when people do not tip or give a really shitty tip, especially if the food is right and was there within the time frame that I told them it would be not to mention we dont have a delivery charge.
