I'm posting this thread here because I think it is a form of witnessing....here's why: Back in college days, my son & his future wife used to work for severe popular restaurants. As part of their schedules they were required to work Sunday lunches. They, along with nearly everybody else at the restaurants, DREADED Sunday lunches because that's when the Christians came in after Church! Why? Because these Christians who just came from church either would not tip or leave little for a tip. Sometimes a table of 10 would leave 5 bucks or so. I don't ever want to be seen as a Sunday Christian tipper, because that brings shame to the Name of Jesus, IMHO. Aren't we supposed to witness everywhere we go and by the life we lead? That's how I feel, anyway. I know it is considered par in the industry to leave 15% (no longer 10%). I always leave 20% to 25%. These servers have to work their rear ends off and live for tips. Not only that, but they might have to share with the bus personnel, too, and maybe the salad person. Just some of my thoughts (no tomatoes please!).
