One of the few exchange offices in Polotsk that is open until 21:00! It is located in a shopping center, there are no queues. The rate, well, probably differs by some pennies from the rate at other banks in Polotsk. Large parking lot in front of the mall.
Gray. There's a queue all the time. I will not say that the cashier is to blame, it's just a place like this, there is always someone who needs to drop the currency.
