Relationship adivce to meeting new poeple in person

I feel like i my mind and myself are kinda misreading people and i had a situation at costa last year where i wanted to try and well get to know someone alot better as she seemed very ncie but i dodn't want to do it at same time. I feel i am ready to start proper dating. howerver i dont want to ruin anything and having autisim really pits people off i think.

The costa worker was called person A. really kind, sweet and friendly. good looks ngl but i never managed to get into a propere convo nor even asked anything. i think she left costa tbh as not seen her there so far. I went in yesterday and saw a costa worker called Person B. got into a convo with her with my mate enjoyed it. but i instantly felt i want to actually propely sit down and talk with her you know. but unsure about it.

I have copied that from a post i made somewhere else befor i found this fourm. 

Edit: didn't fully read the rules to start with. Person A was a person from last year person B is recent person
