Here's three of them...
1. Yell, whistle, or wave money and I'm going to make you wait. Make eye contact and smile, and I'll come over as soon as I can. Know what you want and have your money ready. Don't create a traffic jam.
2. Start a tab. If I swipe your card five times this evening, that's five times as much paperwork I have to do at 4 a.m.
3. You want a drink made 'strong?' Then order a double-for double the price.
VERY interesting looking at the rest HERE
