<human>: Can you give me a shortened version of the text?

So, there's a local shop that I frequent and I've recently become enamored with the shop owner. We've known each other for maybe a month and a half and I can tell he's interested in me (he's slipped in personal questions about if i'm single, how old I am, my interests) and i've been dropping hints to let him know i'm interested in him. 

His shop is never empty. It's the kind of place that the patrons go more for the conversation than to actually purchase anything. I want to ask him out, but I really don't want to do it in front of his customers that always congregate around the check-out counter. How do I broach the subject??!! Would it be cheesy of me to pass him a note with a question on it like "wanna grab a drink?" and leave him my number?

I'm a little more self conscious about this than usual because of our age difference. I'm a 22 year old college kid and he's a 35 year old business owner. Is he out of my league and that's why he hasn't made a move yet?
<bot>: Young woman self conscious about asking out an older man for drinks. How do I broach the subject, or should I just wait and see if he will ask me?
