Why don't we tip bus drivers then? Why don't we tip dental hygienists? Why don't we tip the pilots on our flights or the janitors at our libraries?

The choice of who we tip is entirely arbitrary. How much we are supposed to tip is also arbitrary. There is no logic behind it. The system is entirely stupid.

It clearly existed so that the proprietor can delegate the duty of finding an punishing bad service employees to the customer... which is, again, a terrible system that makes no sense, and it make even less sense now that it's spreading to all manner of jobs where this tenuous connection doesn't even exist!
