TJs crush

i (23F) have a fat crush on a cashier (presumably my age?) at the queen anne trader joe’s but don’t want to be a weirdo asking someone out or giving them my number or whatever else while they’re at work? i know as a woman it can be annoying/uncomfortable when men do that but i’m not sure how men feel about it when the roles are reversed. don’t even know if he’s single or not and if i were to say something and get rejected for whatever reason then i would still have to see him every week when i grocery shop 🥲 wasn’t sure where else to go with this post… help me seattle friends lol
