If you are sitting at a table with people you don’t know,it is impolite to light up a cigarette without asking if it will trouble them.（在美国,当周围坐着陌生人,你不打招呼就自顾自的点烟,这是不礼貌的）
At American restaurants and coffee shops you are usually served cold water before you order.（在美国,你在餐厅或咖啡厅点餐前,通常会提供凉水）
Most cities and towns have no rules about opening and closing time for stores or restaurants,and in large cities,stores may be open 24 hours a day.（大部分城镇没有商店、餐厅何时开门或打烊的规定,而在一些大城市,商店可能会24小时营业）
Serving in restaurants is often too large for many people,so people will ask the waitress or waiter for a “doggie bag",which may have a picture of a dog on it, but everybody knows you’re taking the food for yourself.(餐厅供应的餐食通常对许多人来说都太多了,所以人们会让侍者拿来一个“狗食袋”,虽然上面可能画着只狗,不过大家都知道那是给人吃的)
感觉文章只提供了美国custom的信息,回答却是differences,略有点奇怪.按我自己的理解回答了
