Bad service with management

I've been to the place 3 times this week and had a good experience, up until today. The way the manager treated us was unacceptable. I have been placed by my waiter in a smoking area, according to him. After an hour and a half, the so called manager ask me to leave because it's not an smoking area. I said to her that I've ordered some drinks by a waiter, she said to me I don't have a waiter by that name. There were people right next to my table, standing and smoking but I'm not allowed to smoke at my table. I mean, how must I know where to smoke if I'm not working there? That's why I ask my waiter where can I sit and smoke. If you don't know you're waiters with branded clothes and how to handle you're customers, you are not the right person for that job position. Please come back to me regarding this situation, otherwise I'll take it up with you're head office.
