So, I'm just minding my own business about to enjoy my lunch. A coworker sits at the couch near me in the cafeteria. As I start eating my lunch, my coworker decided it's a great time to start getting undressed and change out of his clothes to a new set of clothes. What I want to know is, is that okay? Why didn't he go into the restroom and change? Should I report this? If so, how do I go about reporting it?
Edit: This is in the back work area. There was no one else around but me. And we're the same gender, but should that even make a difference? Also, this is a public library. He didn't get completely naked. He did leave on a white T-shirt, sky blue boxer shorts, and black socks.
Edit: I've already confronted him about it the first time. I asked why not change in the restroom? His reply was and I quote "It's too small in there". I don't have measurements of the restrooms, (we have have two staff restrooms in the cafeteria area that were empty and could have been used) but seriously, how much room does one need to change their clothes? Yes, I get it's not a big deal, but still. It can be uncomfortable if another staff member walks by.
