Manager very rude

We always go to thia place and order burgers and because we dont eat bacon we always ask to swap it with anything else that have the same value .. today we asked the same and the manager was so rude to us saying that thats how is it take it or leave and refuseto talk to us left us talking and went inside saying your food will be ready in 15 min and he did charge us extra for what we asked to be swapped. The waiters complain also about him being rude to many customers that they loosing. I wont go back to that place anymore
