Отель хороший, а персонал грубый Hotel is good but staff is rude

I can’t say anything bad about the hotel, excellent location to the beach, beautiful pool, food is good. The problem is with tourists. Whether this is due to the fact that most of the guests are Russian - I do not know. If you suddenly misunderstood something, then no one will stand on ceremony with you, they will demand money with stone faces and in a rude manner. To your objections that you were not in the know, they will peremptorily repeat that rules are rules. We had, in fact, a nonsense situation. We had half board and we wanted to change dinner for lunch 1 time, because we were going to dine in the city. In the evening I called the reception and asked if it was possible to do this. I was told that without any problems you can change dinner for lunch. The next day we went for lunch and then in the evening for dinner. To our surprise, at dinner they began to demand payment for dinner from us. At first we did not understand anything, because we have half board, and lunch was instead of yesterday's dinner. The manager of the restaurant (a Cypriot named Christos) explained to us that you can change dinner for lunch only ON THE SAME DAY. We didn't know this. And when I called the reception, they didn't tell me about it. . When we went to the reception to explain our situation, an elderly Cypriot (with some strange hair color) rudely began to shout that it was FORBIDDEN to transfer dinner or lunch to the NEXT day (I literally translated - he shouted "it is not allowed"). On my arguments that I called, he did not react in any way. And by the way, he was the one on the phone with me that day, he just didn't understand that I wanted to move dinner to lunch the next day. Then, a red-haired middle-aged lady (apparently a manager) with an unfriendly face appeared from somewhere and categorically and loudly said in English "That is not acceptable". Then we realized that it was useless to talk to them. I don't mind the money I ended up paying for dinner. It’s not even the fact that I misunderstood the rules (by the way, their memo doesn’t say that you can change dinner for lunch ONLY on the same day), but I was eventually ripped off for dinner. It is outrageous that they spoke to me in a rude manner at the reception because of a situation that is not worth a damn. I was given to understand that for them I was a nonentity who had come from Russia and they didn’t give a damn about anything. The overall impression of the hotel was undermined. How can a good 4-star hotel have such rude staff - I don't understand.
