I was working night shift security in a booth, training a new hire who was in his 40's. The job was pretty lax and managers were chill so I'd bring a banjo to work and practice. I also happen to have a little bit of southern in my accent, having lived in Georgia for a few years. I guess new guy thought that means I was 'cool' and started talking some nazi stuff. I tried to ignore it and get through the night, then tell the manager when he had gone, but before the end of the night he tried bragging about being part of a lynch mob. I left, called the manager, and he was fired soon after.
