How can i get his attention?

so i work at a tim horton's (not the most glamorous job,i know) and there's this one customer that is really hot and i would really like to get to know him somehow. i am a fairly shy girl and i don't know how i can get his attention. the last couple times i served him,i had his coffee all ready for him by the time he got up to the counter,showing him that i remember his order. i believe one of the ladies i work with might know him because i think i remember her calling him 'adam'...but it's possible that it was a different customer cause that was a while ago,before i really started taking interest in this guy. what would you do in my situation? i don't know if he's single or how old he is (im guessing mid 20's...im 19 btw)..any advice helps! : ) thanks
