Thong sighting!

Last week in the gym changing room, I was getting changed and I heard the door to the tanning booth open. I glanced up and out walked a very trim mid-twenties guy. I had a front view first and he was sporting what I thought was a skimpy black bikini brief. As he turned to walk to his locker I saw it was in fact a thong! Obviously going for an all over tan! I'd not seen him before and haven't since but here's hoping!
