英语翻译
The bill (often called the "check") comes usually with tax added but no service chare-though some restaurant do now add a service charge.The etiquette(规矩) books say that you should leave a ten per cent tip(小费) for lunch,fifteen per cent for dinner.The tip should be calculated on the basis of the total before the addition of tax.
就是第一句话,tax added那不会翻译了,

账单(餐馆中常称为“结账单”)通常含税,但不含服务费.当然,有些餐馆现在也是会把服务费加进去.根据餐桌上的规矩,吃完午餐后应该给10美分的小费,晚餐则需15美分.小费金额通常根据结账单上不含税的总金额而定.
