The site indicates a high exchange rate, as soon as you try to exchange, they say that the information on the site is allegedly incorrect, probably has not been updated (although even after specifying the problem, they do not update the exchange rate) and offer to exchange at a significantly low rate. That is, I assume that they are playing on the fact that a person has already come a long way, got to them and is unlikely to refuse to exchange even at a low rate.
The bank looks like it's not very solid, one window, no closing doors, how much you change, everyone finds out, it smells like smoking, like in a smoking room, it feels unpleasant, the exchange rate is good
