Bad service and rudeness

On my second visit (the first having been pleasant enough) the manager lashed out at me in front of my guests. We were supposed to be out by 2pm, although they had no guests coming in. We were braaing and it took longer than expected. But we weren't troubling anybody. Anyway, it seems someone complained and the manager came down on me from a dizzying height. She even threw in my face the fact that she had given my visitors a discounted rate! She was rude and petty. I think she hoped we would drive off after dropping the key. So she hid away when we knocked at the front office. It was only after phoning her that she opened for us. She seemed sheepish and made some excuse about needing a holiday. We offered to pay the full price for the visitors, but she was having none of it. She then went on to withhold the deposit, claiming that we broke a kitchen door (it was broken when we got there). They obviously need training in customer relations.
