If any of you are of the notion that Americans the cultured people and have the art of not looking like an uncouth slob, then better be informed that many of their behaviours and culture do not go well in rest of the world. Here are lists of American behaviours which accepted in their own country but is considered rude in other parts of the globe.
Americans follow the style of tipping at restaurants and bar. If you don’t tip in US restaurants then you are likely to become least popular person and will be hated by friends, servers, restaurant owners. But in Japan it is the other way round. Excellent service is expected even without additional tips or incentives which are already calculated in the bill. Tipping seems rude in Japan.
