I'm very disappointed in your behavior regarding payment security, anywhere in the world require me security for payment, as you require excessively, I pay you with my credit card and you do not need to be concerned payment that you have my credit card number for charge.
Yesterday it very irritated me off payment RMB 101.00 cash for my lunch. And even more angered me that you withheld from me calling on the phone in the room to USA, about it coming you score 0.
