I have been living in the US for years, but I am not from the US. Over the past two years, I have greatly reduced the purchase of coffee and the like in coffee shops and the times when I eat outside because I am turned off by the tipping and the murkiness of the final price. When I see $10 as the price of the item I am buying, I expect it to be the final price. Instead, surprise! I have to add taxes, tips, and the cost of the air I breathe. On the one hand, I don't want to be "culturally inconsiderate" and not tip; on the other hand, I don't have the same bovine acceptance toward money and spending issues that unfortunately many Americans seem to have -- see, for example, health care spending. I have therefore decided not to contribute to something that makes me uncomfortable. I wish many more people would say no.
