I think he was rude. He was interested in meeting you but then it sounds like it didn’t click when you’ve met. Polite person would still give full attention and maybe would make a new friend. Rude person was letting you know with his body language that he wasn’t interested in you upon meeting.

I think it’s a blessing that you didn’t have to see him more than that one date. Imagine a waste of time it would be if you had to see him more. His loss.
