Does Promising a Higher Tip Mean Better Service?
It shouldn't, but it usually does -- especially if you're a regular patron. Servers live off of their tips. Isn't Santa nicer to good boys and girls, too?
No, the person that says that is usually the one that runs you around the most and then finds an excuse to stiff you. Tipping upfront is a different story.
God only knows, but I'd be pretty insulted if I were a server and someone asked me to take better care of them and flashed some cash at me. Not saying I wouldn't do it, though.
Not necessarily. There are no guarantees in this business, but most importantly, if a server is thinking that he/she should only deliver their best service for a customer based on the promise of a large tip, they're in the wrong business. Not everyone tips well, but sometimes the biggest tips come from people you'd never expect.
