This is where my head went, and I was thinking they were in the locker room at the workplace/university gym or something.. I honestly donno why that came to mind before laser hair removal did.. 😂
(E: I've even had laser hair removal myself, but there was no towel involved, but a gown type thing, maybe that threw me off. I also think my brain inserted the word "friend" after "tech" when it clearly isn't there lol)
