I'm not advocating for the abolishment of tipping (I explicitly stated this btw), but I am against its expansion and an economic system where bribery is required for an employee to take home a living wage. If we had a social standard where everyone was making at least a living wage then I have no problems with you wanting to depart with extra cash. No one here is really advocating for making tipping illegal, we just don't think it should be used to supplement income.
