I get why this is a good idea/concept. But then I think about the possibility of not being able to pay my bills because I wasn't getting paid enough for whatever service I provided because not enough people deemed it valuable. The subjective nature is what I struggle with.
I worked in the restaurant industry for way too long. And this one of the reasons I will never work as a server again. I don't want to rely on someone's whim to be able to pay my bills. And because of that I usually over tip my server when I go to breakfast. I don't ever put the tip on the credit card either.
