When a stranger is rude to you, should you let them know?
If they walk away, I might mutter something loudly, so they'd give me a dirty look or something..depending on what they said
I go into smartass mode. ;)
Probably but the possibility of my doing that is fairly low. They would need to be awfully rude for me to actually react.
I usually smile.
Sure say something. Hey, I didn't mean to ruin your whole life, or Is it me, of is something really bothering you? Something light to give them a chance for a do-over. If they screw that up too, there's no need to waste your time with them.
