I had a supervisor walk past me at the employee gate where I was working bag searches and metal detector. He brought someone through and dropped him off at the media credential window. I was telling that there was nobody there giving out credentials. Then when he walked back through the metal detector, he starts moving the charging device that operates the metal detector closer to the metal detector. I told him that it can't be placed too close to the detector because it will constantly set it off. He then turned to me and yelled at me to be quiet and calm down. He was yelling at me at the top of his voice. And then he just walked on The sad part about it is that he has done this to me in the past. And yes, I was calm before he came by and after a few minutes, I was calm after he left. Oh well......
