The difference between European and Russian culture are so great that many books could be written about them. Precisely, among some main points that the differences we have:
Hospitality and food
Food and hospitality are practically the same in Russia. If someone has guests, there will be a lot of food that they put on the table at all times. The variety of food on offer is seen as a measure of their hospitality.
Once the meal begins, they may not refuse any food or drink offered as this will cause offense. The hosts will continually offer more and more food. It is customary to fill a customer's plate, even if he / she has insists that they are full.
It is normal to share things like cigarettes, food or drinks with other people, even strangers with whom you may share a train car.
Label
If you are lucky enough to be invited to the home of a Russian family, you have to bring them a gift. Wine or cake is suitable for this. Flowers are also popular, but make sure that the total number of flowers contains an odd number of them, as an even number of flowers is for funerals. And be prepared to remove your shoes at the door.
Another detail is that in public transport you have to offer the seats to the ladies. It is also customary to offer a hand to women to help them get off public transport.
Public transportation
The best, fastest and cheapest mode of transport to explore Moscow and Saint Petersburg is the extensive metro network. It is efficient and cheap. The costs are about 140 rubles for 10 trips in Moscow and 160 for 10 in St. Petersburg (prices are approximate and subject to change).
All types of attractions and tourist sites in cities have a nearby metro station. These days, the names of the different stops and stations are given in English.
