Rude behaviour

I came to news cafe with my husband and we sat for a few minutes waiting for service, I eventually walked down to look for a waiter and bumped into one of them walking up the stairs. <br> <br> I greeted her and asked her if she was the person that was going to serve us and she kept quiet, I greeted her again and asked her again and she turned to answer me rudely saying she will serve me if I really want her to serve us so badly. <br> <br> I then decided to leave, on my way out I talked to a person that looked like the manager (in a black shirt) telling her what happened. Then one of the waiters(Tshepo) talked me out of leaving and said she will serve us.
