I must say I'm a little appalled that management is not squashing down on this type of thing, unless, perhaps, they sympathize, or letting staff place a tip jar next to the cash register makes it easier to deny a raise because, "after all, you have your tips."

It's yet another example of how poorly trained labor is today. In my mind, this is precisely where the notion that cheap labor is better than more costly labor breaks down. If you paid your staff better, they would probably be more educated and more motivated to do a good job.
