After going to this place about once a week for lunch, I've developed a bond with the manager, and he always hooks me up with discounts.

This cute girl who also works there might be the manager's sister or cousin or just another worker. She's always nice to me, but hey the manager runs the place extremely well, so I would expect she's quite nice to everyone.

Without knowing her age (I'm sure she's well over 18, but I'm in my upper 20s), her relationship status, whether she's very close to the manager, and whether she's even interested in me... is there any way to proceed? Asking for her # when the manager and other employees are always within hearing is surely unwise.

I don't want to fuck things up or make things awkward with any of them because I'd like to continue to get food from here about once a week. Perhaps it's not worth the risk when there are literally tens of thousands of other girls in the city to hit on.
