Is this all flirting or friendly?

If you meet as a group, everyone else leaves and you are the last two left does it mean anything?

He remembers small details about me like the necklace I wear, how he knows its me coming up the stairs by the way I walk. He also guesses the drinks I like and jokes about my height. Is he just insanely in tune and has a great memory or is the trying to flirt with me.

I'm just intrigued as to where this is coming from as I can't figure him out. Any insight would be super appreciated.
