Yep, went horribly wrong though.
I figured it would be inappropriate as his boss to make a move at work, so I decided to keep it to myself and not stir any shit. Then one day I saw him on grindr, so I sent him a message so that he knew we were on the same team, and it was a completely innocent "hey, it's me from work" kinda deal.
Well that was a horrible mistake, he blocked the shit outta me and basically ignored my existence for about two months afterwards, wouldn't even give me a second of eye contact, would walk away from me when talking to him, would leave the room when I walked in, etc. He was out at work, and I knew he was gay as soon as I met the guy, so there was no issue there. We worked the same shifts so it was super awks after that until he quit two months ago for unrelated reasons. Meh.
Moral of the story is: he has major social issues and missed out on something potentially good, and I will NEVER make that mistake ever again. =/
