The amount of complaining about tipping baffles me. Tipping is a progressive form of price discrimination, where the added profit goes straight into the pockets of labor rather than capital. Meanwhile, as the customer, I effectively get to bid on the quality of service I receive. One just needs to go to a restaurant in Europe to recognize the vast gulf in quality of service compared to the US, with tipping being the big difference.
