Nver ever going to spier again, ill treatment

We received the most terrible,ill treatment form the assistant wine amanager that one can ever imagine. 30/12/2019 We visited spier and where we seated there were glasses which were broken by the windy weather, it took the wine assistants an hour to clean up, we moved and order a bottle of wine, the wine educator which was assisting us went to another tables to assist, and when we requisted the glasses from the guy who came to where we seated he told us he cannot give us the empty glasses which we needed as we wre not helped by him and he does not know what our agreement was with the lady who first us, we tried to tell him that we only need empty glasses does that requires some osrt of agreement and arrangment , he had a very i dont a f look on his face, and when we trued to report him we were told he is the assistant manager i guess he should treat guestes like that.
