求帮忙概括英语文章段意
to avoid getting confused about the British tipping system,you need to check your bill to see if a tip is included or not.if it is not ,i suggest leaving 10% of the bill for the waiter or waitress--even a bit more if the service is good.talking of money--it is really easy to exchange traveller's cheques at banks or hotels so i advise you to get some of those before you come.
