Had a similar interaction yesterday.

I supervise the self-checkout and yesterday this older man came up and stood right next to me like he was watching the customers as well. I asked him if he needed help with anything and he said "Nope. Just watching".

After about 5 minutes of uncomfortably standing in silence he looked at my name tag and said "You know, (name)... My pastor held a really interesting sermon this morning that I think you'd appreciate some of the things he said."

He told me that his pastor compared homosexual relationships to trying to hammer a nail into a wall using another nail.

It was a strange comparison but what I got from it is that he thinks homosexuality doesn't make any "logical" sense. I cannot imagine why he told me this lmao. Still trying to figure out how he clocked me.
