Worst service and attitude from a Manager

The waitress lacked product knowledge and they ( manager and waitress) were very quick to say they couldn't serve us ultra mel and ice cream, instead of saying we can but with an additional charge. The Malva pudding they served was under cpoked so I asked the waitress to check with the kitchen for us, manager cam back instead and told us without checking the oudding that all the puddings come that was, I advised that I had never seen or tasted one like that, he said no that was how they came so we asked him to bring it back. He then said the kitchen had probably trashed it because he didnt allow staff to send food back to the kitchen. He went to check but never came back, waitress came back with another Malva pudding to what she left with a quarter of a malva pudding. This pudding was cooked through out so I went and called him, he wasn't impressed that I was calling him.he came non the less. He proceeded to tell me that I was taking this personally and that he wouldn't speak to me. That as a chef he was ofended. I told him it was ok he could go. he ignored me and spoke to my partner as if I didn't exist. I told him he was being unprofessional. He got very heated and left
