So I have a crush on a girl I work with and I wanna make a move but I wanna be respectful and not put her on the spot. She’s very energetic and friendly but also seems like she could get uncomfortable easily so I’m being super careful with how I do this

She comes to my register a lot so if I waiting till she comes again and said “hey you’re super fun to talk to and I’d love to talk outside of work, would you mind if I put my number or snapchat on the receipt?” Is that a good way to make a move?

Or is just asking for her snapchat after a good conversation better? I feel like it’s less special but it’s more casual 

I feel like it respects her and keeps it kind of causal. What do you think? And if it’s not ideal, what’s the ideal way of doing it?
