Hanna, welcome to the Russian reality
In fact, it's very good to say 'thank you, please', etc. But all depends on education and upbringing here. Some people in Russia are not used to hear 'please' and 'thank you'. When you say thank you for example, to кондуктор when she gives you a ticket she is sometimes shocked to hear 'thank you' for the ticket!
Also about the queue...when I was in London and was waiting for a bus, there was the queue and an old lady was behind me. I said to her smth like 'please go first' and she said 'no, no you are first' I felt so uncomfortable that because of the 'rule' of the queue the old lady didn't go first. In Russia it is polite to let people who are much older go first.
