I don’t think it’s that challenging. All one has to do is avoid all sex-related threads. Out of sight, out of mind.
I’ve had a woman ask me to try and seduce her husband because she thought he was gay and in denial. So it could certainly be worse than an offhand comment.
I don’t know – Nashville’s not that big and those guys will probably return to that Subway at some point. OP, how busy are you?
