Tips were first used as a way for rail lines to avoid having to pay black coach attendants a wage.

It isn't surprising that service workers don't want to abolish tips, since that's primarily how they get paid now - but that doesn't mean we shouldn't abolish them. The owners should have to pay their workers a living wage. By making that the consumer's responsibility, it frees the business owner from the responsibility of paying their workers for their labor.

Tip wages are exploitative, plain and simple.
