I agree. It's a sheetty system because it's only set up so that we pay most of the salary of the wait staff. Tips aren't really rewards for good work, they are what people in that business depend on to make a living. It's really salary for them.
But, it would be nice to be able to reward the kitchen for doing a great job. I do understand that some places do have wait staff share tips with the entire staff including the kitchen, but I hope those places pay the wait staff more than minimum wage to start with.
