While going for a walk, do not take much money and valuables with you. On the streets of the city it is recommended to avoid large crowds of people as these are the most favorable places for pickpockets. Camcorders and cameras are best to be worn on a strap over your shoulder or fastened to your belt.
Buses remain the most accessible way of getting around the city as taxis in London are quite expensive.
Most restaurants include tips in the total bill. As a rule, the tips here range from 10 to 15%. Leaving tips in pubs is not common.
Under no circumstances leave your personal belongings unattended, even in a car that has been rented. Special guarding parking is the best place to leave your car as there are quite many car thieves in London.
Local residents are distinguished by politeness and restraint, so visitors need to reciprocate any sign of attention. In the stores you show greet the seller; make sure you hold the doors when entering or leaving the premises, and if someone helps you, you certainly need to thank.
