How to get this guy's number or give mine?

VK1997
I suck at flirting and trying to hit on people lol but for the last few months I've been going to the Starbucks next to my office and I totally have a crush on one of the guys that works there.

I did comment on a pin he had on his uniform because it was from my favorite movie but that's it. Every other time I just freeze up. The last time I was there (after the comment I made) we kept making eye contact with each other so it felt like maybe he had some interest in me too.

Anyway, how should I go about either asking for his number or just giving mine? Is that appropriate to do while he's working?

I was thinking when I got my receipt from him I could quickly write it down and hand it back to him or just come in with a note that basically says he caught my interest and here's my number?

Any tips or ideas are welcome.. please!! And thank you Lol
