There are only 2 employees who can issue payment cards. The queue is more than 10 people. Each person's service time is about 5 minutes. In general, it will take at least 30-40 minutes to wait...
Currency exchange operates in the cash register mode for all transactions. Accordingly, if you want to exchange currency, you will have to wait 30+ minutes, which is very inconvenient, I strongly do not recommend it.
