As at all post offices in Minsk, there is a queue for coupons, clean, calm, exceptionally polite Belpost employees. And there are practically no queues, during the day rare visitors come in or 1-3 people at most.
Politeness is already a characteristic feature of Belarusians!
They work very slowly. Earlier, you take a coupon for the parcel and you can receive the parcel and the transfer. Now money transfers are separate. You need to queue up. A madhouse. There's a 40-minute queue plus another one to wait for. And two cash registers have been stuck in the past.
