Commissions and tips are totally different. Commissions are based on an amount that must be paid. Tips are based on the customer's constitutional right to give his money to whom ever he chooses. It's called liberty. If you cannot see a problem with stealing other's property then you have a problem. The problem is customers are tipping employees only to have the business financially benefit itself to the customer's tip through the tip credit. If businesses need to benefit more from their customers then they should raise their prices not steal their employee's tips.
