Heeeelp *especially ppl in retail*

okay so I have a MAJOR crush on this guy who comes into the shop I work in. I work in a really quiet shop so there's not much to do and no young people come into it because it's a book/stationary shop but he comes in every Saturday and we chat and he buys stationary (he has alot of pencils now 😂) but he's super cute and only ever talks to me and goes through my till and flirts ALOT. like yesterday there was a queue and it would have worked out that he would be served by my coworker if he queued so he literally waited around the corner for like 5 minutes for me to be done with an elderly customer and he walked straight to me not even looking at my coworker😭😍 after he left she was like omg that's the guy?!? I can't stop thinking about him but I know alot of people can just be overly polite so I'm worried it's just him being him and not liking me in that way? Idk I wanna hear anyone else's story/experience with a customer!!
