I just finished a 10 day motorcycle tour up north. We got the full range of customer service. From happy to see you, to pay the bill and f off. I will always remember the thai staff/owner who didn't speak English but did everything to make our visit as pleasant as possible. Then there were those that understood a simple request to slit the bill into 3 individual bills but didn't want to do the work and bought one single bill and had us figure out what was what. 3 bills, equal 3 tips. One bill equals no tip was our message to them. And I'm a tipper. But not when they don't care. That blank stare and f you smile doesn't go very far with me.
