Happened to a friend who worked in a shop. Vagrant looking chap walks in and the other staff walked away. He just went up and started talking and also had the knowledge to answer all questions. Vagrant starts placing his request and friend said manager came out and started to ingratiate and wasn’t happy with response of “I refuse to talk to anyone else in here due to attitudes but if you want to make the big sale, you will leave me alone to talk to the gentleman who didn’t judge”. Nice commission for not being an asshole
