Here's a story about tipping:
My buddies and I were in a cow field....wait...wrong story.
A buddy and I went to have dinner when we were on a business trip (No, not a man date) and got seated. When the waitress came up she asked how we were doing and we said "good" then asked how she was doing, she said, "ok." Then I asked, just "ok," what would make you respond with "good?" Then she said a $100 tip and started laughing along with my buddy and I.
A couple min later she came back with our drinks and was talking to us. She then asked, "are you two brothers?" Which my buddy promptly replied, "Why, do you have a fantasy about being with two brothers?" This caused me to almost spit my drink across the entire restaurant, but luckily I was able to avoid that. But, it caused her utter embarrasement. She was soo afraid to ask us anything after that. After many akward exchanges, it was finally time for us to pay the bill. We felt so bad to embarassing her that way that we left her that $100 tip.
