Being a waiter can pay as much as a professional, if they are good at their job. Those advocating for set wages don’t want waiters to earn as much as they. That’s what it comes down to.
In the article the real reason for the change came sneaking out. The owner complained that with tips the waiters were making more then she was and that was just not fair!
Needless to say the good wait staff quit to work some place where they could get those nice tips again.
