Britain is extremely expensive and London is horrific （惊人）. While in London you will need to budget（财务预算） about US$35 for bare survival (dorm accommodation（住宿）, a travel card and the most basic sustenance). Even moderate sightseeing（观光） or nightlife can easily add another US$25 to this. If you stay in a hotel and eat restaurant meals you could easily spend US$90 a day without being extravagant（奢侈）. Once you get out of the big smoke the costs will drop, particularly if you have a transport pass and if you cook your own meals. You'll still need at least US$30 a day, and if you stay in B&Bs, eat one sit-down meal a day and don't stint （吝啬）on entry fees, you'll need about US$65 a day.

Travellers' cheques （旅行支票）are widely accepted in British banks and you might as well buy them in pounds sterling to avoid changing currencies twice. Change bureaus（办事处） in London frequently levy（征收）outrageous （过多的）commissions （佣金）and fees, so make sure you establish any deductions in advance. The bureaus at the international airports are exceptions to the rule, charging less than most banks and cashing sterling travellers' cheques for free. Cashpoints (ATMs) are very common in Britain: most are linked to major credit cards as well as the Cirrus, Maestro and plus cash networks, but if a machine swallows your card it can be a nightmare. Most banks insist on chopping（砍）it in half and sending it back to your home branch -- very helpful.

If you eat in a British restaurant you should leave a tip（小费）of at least 10% unless the service was unsatisfactory. Waiting staff are often paid derisory（少得可怜）wages on the assumption that the money will be supplemented （辅助）by tips. Some restaurants include a service charge on the bill, in which case a gratuity（小费）is unnecessary. Taxi drivers expect to be tipped about 10%, especially in London.
