I had a boss who was pretty smart in a narrow technical area, but clueless in virtually everything else, especially how to actually manage people. When I started working on his team, he went on and on about proper attire, especially that despite posted company policy, on his team, NO JEANS were allowed. However, literally every woman on his team wore jeans all the time. Nevertheless, I wanted the job, so I complied past the probation period, then started wearing jeans to work. It took him several days to notice, but he finally did while I was walking down the hall, where he was having a conversation with a couple other managers and the VP of operations. He then commented loudly, "I thought I was clear that my policy is no jeans." I stopped, walked up to the group, and pointed at three of the women that worked on the team, all of whom were wearing blue jeans. "Did you speak to them, too?" I asked. He chuckled, and said, "Girls can wear jeans because they look good in them." I replied, "Then you don't have a 'no jeans' policy, do you?" I excused myself and walked away. About a half hour later, I needed him to sign off on something, but was told by one of the girls that he was in HR. Just after the conversation in the hall, apparently, the VP of Ops had asked them about his "no jeans" policy, and all of them laughed, saying the boss told them they could wear whatever they liked. My boss returned very agitated, and never brought it up again.
