The exchange rate is slightly more profitable than in the neighboring exchanger, but they charge a 1% commission. At the entrance, when I asked if there was a commission, they replied that there was no commission. And when they already receive the money, there is a service fee in the receipt. You start swearing, they turn away and start accepting other visitors.
They take a commission. But they don't call it a commission, but some kind of "tax". Therefore, to your question: "Do you take a commission?" they say, "No," and you give them your money. And then you see a strange amount of deduction in the receipt, but there is no way back. The most correct thing is to calculate the amount yourself in advance and ask the employee to show you the amount due on his calculator. That's where you'll see the discrepancy.
