<human>: How do I ask out the cashier at subway without making her feel uncomfortable?

Long story short, I'm (22m) incredibly infatuated with the cashier at subway. I want to ask her out on a date. Is it better to just straight up ask her? A note asking her to text me seems less intrusive..but in my opinion seems..weak? I don't know if that's the right term, but you know what I mean. Flat out asking her on a date infront of her coworkers and customers seems so disrespectful, but I don't think there is another way. If I get embarrassed, I can leave. She cant. Any ideas are appreciated.

Give me a shortened version of the text
<bot>: I don't really need advice on what to say, I've got that covered..I just don't know how to do it politely to someone who's working.
