I agree. American influence has at least made people aware of the concept of tipping basically everywhere in the world. However, as I stated in my original post, I have seen first hand local people become offended by people tipping.
I can remember a particular instance in Phnom Penh, Cambodia. It was the first meal I had after arriving there and I admit, I didn't check online, so I just went with what I thought was the safe play and left a tip. The very young waitress looked pissed and went and got the owner (who I believe was her father) who came back and yelled at me. I learned my lesson to make sure to check first.
