The master was rude, and when asked to provide a book of comments and suggestions, she refused. Besides, I've never seen a cashier's check. Not another foot.
It seems that the quality of the haircut depends more on the mood of the master. I won't say anything about the quality of the "tool", it seems to be normal, but the quality of the haircut itself is lame. In fairness, I will say that one master did his job at least 2 times in a row normally, but the second master did it anyway, and more than once. The price is reasonable - at the moment 8 rubles.
