Granted this man had a closed sign out but it was placed over his menu. His doors were open and lights on so I put my head around the door and asked nicely if he was still doing coffees. I not only got a tirade about not being able to read but he followed me outside and continued shouting at me. I suggested to him if he was closed he shut the door to which he yelled "SHUT YOUR MOUTH" I have a feeling I was not the first to think he was still open!
