Sergey, hello, you are currently traveling around the North Caucasus. Tell us how the payment is there, asking for cash everywhere, even if there are payment terminals? While on vacation in Adler and Dagestan this year, almost everywhere, if there were terminals, they asked us for cash, but luckily they did not refuse non-cash payments. I don't carry cash. I have a card and I pay with it. In all the cafes we were in, I paid accordingly. Buy food by transfer to a private person's card if they require cash without a receipt, etc. i don't like IMHO, anyone who casually circumvents the law will easily slip rotten meat to save money.
