I put 4 because the attitude when receiving money was strange. I came in the morning, they refused, they said no money, although they gave it to the locals in front of me. I arrived later at 16:00, got to the same cashier, apparently this saved me. I asked now, I hope there is money? She replied with a smile, yes. Although before that I saw a Russian girl refused in another window, the mood was to quarrel, I can't walk several times a day. However, they gave me the money. When I started to leave, one girl was refused. It's very strange.
