The service and staff... well, you are generally not welcome here. But you have to work somewhere, so they serve you. However, in Minsk, almost everywhere with such persons (offices of mobile operators, cash desks and canteen handouts, supermarket cashiers, museum reception, GUM sellers... they are all kind of unfriendly, unsmiling, as if civilization has pulled all the vital juices out of them). There was enough Russian gasoline (it is cheaper), so I did not check it.
