The failure of the great tip-free restaurant experiment

Imagine not being paid enough to do your job. The service industry in the US is stacked in favour of the business running the service and it's employees rely on their patrons to make up the rest. 20% is an unbelievable amount in my opinion but what's worst is that these experiments to do away with tips are failing. Employees should be paid appropriately by their employers and there should be nothing else to say on the matter.
