they didn't give me a ticket for my coat, but they wrote my initials on the hanger. At the end, when I wanted to leave, they asked me for my ticket, but since I didn't get one, I just gave my initials. That wasn't enough for them though, they wanted me to wait until everyone left or just pay them $10 to leave right away. I was shocked, it was practically robbery.
