The Ant and the Grasshopper.....

[Copycon]

I never tip, I expect the guy/girl to have a salary, if he/she does not, it is not my problem. I can save that money in the bank and let it work as venture capital, working as a base for new small businesses that in time will prosper and will after a while be in a need to employ people. That gives people more freedom to choose!

 

Edit: By the way, people working in diners are poor and stupid, so not giving tip actually just gives them an incitement to educate themselves and get a real job.
