Someone I met today was very polite.

I guess I'm not used to polite people in retail. This man asked about his product and I mentioned he needed an appointment.

"How would I make an appointment?"
"If you don't mind waiting, I can give you our business card."
"I don't mind waiting, I would like the business card."

So I gave it to him.

"Thank you very much, I really appreciate you helping me out."
"No problem."

It was like the most ideal and perfect interaction. So bizarre.
