If that's the case for tipping then why aren't all service jobs "tipping jobs"? I mean you wouldn't tip at mcdonalds, right?

And why don't people tip bus drivers, airline check in clerks, the counter staff at Hertz, etc.? Some check out operators in supermarkets are more efficient than others, should they be tipped?

What is it that makes restaurant and bar staff special?
