[originaltext] In large cities, for instance, London, and crowded places such

In large cities, for instance, London, and crowded places such as airports and stations, there is the risk of theft. (15)We don’t want you to suffer the distress of losing important documents and valuables as soon as you step on Britain soil, so there are some important do’s and don’ts. Don’t carry more cash than you need for daily expenses. (16)If you stay at a hotel, do ask the manager to keep large sums of cash, documents and valuables in the hotel safe and give you a receipt for them. This is a free service. If cash is stolen, it is very unlikely to be recovered. Do keep separately a note of the serial numbers on your traveler’s checks, so if they are lost you can inform your bank. Do take particular care of bank and credit cards. If you don’t want to carry heavy luggage around with you, you can leave it in a luggage office at most large stations and pick it up later. Keep the receipt so that you can reclaim your luggage. (17) If you lose anything, go first to the Lost Property Office at the airport or station, as it may have been found and handed in. If you lose your luggage in the street, or suspect it has been stolen rather than gone away, find the nearest policeman who will advise you on what to do.
