I think western Belarus is closer to Poland culturally and girls there are not afraid of foreigners approaching them in the street.In eastern Belarus girls need the relative safety of the club where the foreigner has at least passed face control and has paid to enter the club.Girls feel much more safe there and are much more open to approaches.They also hope for a secondary benefit eg drinks that is why they are reluctant to reject the guy approaching.
The problem with western Belarus is that the cities are rather small(in Brest everything happens in one small central road paved) and one becomes very fast known there you lose anonymity very quickly.
