upon arrival i was asked for a deposit which was not mentioned when i booked on booking.com the front desk staff initially meant 20% of the amount of my reservation then a few minutes later without to know why we went to 25% obligatorily by credit card. I specify that at this date (one month after), the deposit has not been returned to me yet. for the room, I wanted to pay in cash, a superior told this employee that the cash payments are at the Check out . (and yes sir I understand very well English) I saw the head of the employee to decompose and went to lock up 5 good minutes with his boss (surely to negotiate that I pay right now for fear that I run away without paying since I AM BLACK)
