I just read this article and I am very thankful that this guy took the time to write it. American consumers are (most some of the time) a bunch of little cry babies. Use some simple common sense, and curtsey and you will be ok!!!
Oh, and while I am on the subject of etiquette, if you are on the subway don’t assume the train is designed just for you. Maybe get out of the way of the door so people can get on and off. or maybe don’t sit like you do at home taking up 4 spaces on a bench that can seat allot of people if you would only move your fat ass! Now I feel a bit better.
