Asking out someone who works in retail. I also live nearby and go in there regularly.

I want to ask this girl out and I've read a few posts on here that recommend just leaving my number or IG so I don't put her on the spot while she's working which does make a lot of sense, but the thing is we already have a pretty good rapport, we know each other's names, we've chatted about all sort of stuff while I've been in there so it's not like just seeing a cute girl and handing her a phone number. She has coworkers but usually when I go in there she's working the place on her own so it wouldn't necessarily be a case of having to respond in front of other people (unless another customer is right there).

If she was a girl at a bar I'd just ask her for her number without second thought but because she works retail there's a chance our rapport is just her being nice to a customer and because I live nearby and go in there regularly I also don't want to make her to feel any pressure by that. To be honest if she said no or ghosted me I probably wouldn't go back in there out of embarrassment lol

Any advice welcome, thanks.
