If police were involved and store management is aware, there is more to the story. Because he laughed about it doesn't necessarily mean he thinks it's funny. It may mean that he isn't comfortable, either. To the point that the women are uncomfortable, I can totally see that. I have to take my adult disabled son into female restrooms. It is not a comfortable situation at all. I don't have an answer here except to reiterate that since the OP has not been violated, does not appear to be female (by name of Amaazingdude), etc. that it is not his business. That female coworkers are dressing in the restrooms without using the stalls (giving the person an opportunity to stare them down) makes me wonder why they are doing this. If I were a guest, I would find this to be inappropriate, too. I also wonder why guests have not complained about a man in the restroom. You're also right, Ethics Demander, high functioning ID (intellectually disabled is the currently most acceptable term) people make others uncomfortable simply because they usually appear to be typical, but do not necessarily follow or understand all social mores, upsetting the status quo.
