Theres this girl at my local pharmacy who is 100% my type and always giving me IOIs (trust me i know that retail workers are supposed to be "nice" but i can tell this girl is genuinely interested)

The problem is, when i enter the pharamcy Im only there for 1 minute. I get my stuff then leave, I dont have a chance to speak to her. I see her there but there is rarely an opportunity to talk

Should i do some shit like ask her for help with a product then strike up a convo? Genuinely dont know what to do in this situation.
