On a trip to Paris, my wife & I stopped at a nice outdoor / indoor cafe like they have for lunch....The waiters we're almost stereotypical in dress and manner.....The meal was nice and we were getting ready to leave..... I'd already paid & given a nice tip, however my wife didn't want the coin change as we were flying out and counted, stacked it nicely at the center of our table as a nice gesture to leave for our waiter.....
He came to our table, looked at the change, picked it up and flung it across the table.....He then took his stereotypical movie like poofy waiter self, turned on his heals and stalked away.....
My (Thai) wife was wide eyed astonished as I was half laughing & half ticked off....She looked at me and all she could think of to say was "that's perfectly good money".....
I laughed, but felt bad for her at the same time as she genuinely thought she was doing something very nice for this other person....
She does not tip in Thailand (very rarely if a birthday or celebration)....
I can still envision the shock & look on her face....
