Disappointed and Unhappy

My colleagues and I went to the restaurant for lunch only to leave with empty stomachs. We were 1st judged because were in uniform and they assumed there's no tip there(my view). Then the manager TINASH gave me attitude for asking for the staff menu as we are taken as staff because we work in the same gated area. He was rude and went as far as coming to my manager and telling me I'm banned all because I asked for the staff menu. What's worse he tells his colleagues that we are full of **** and he'll prove a point to us. Now we got warnings for that. I'm truly disappointed in their service. He didn't want to help us from the word go. Boycott Papachinos Silver***es because the management lack manners and respect for paying clients
