<human>: For the past couple of months, I've [29F] become friendly with the cashier [20M] at my grocery store. I end up at his register and we make small-talk at least once a week. 

We have the same sense of humor, make the same type of jokes, watch the same shows, listen to the same music... Since we connect so well, I really want to become friends with him, but just as friends. We're both single and I don't have any romantic interest in him at all.

I can be super awkward and this is gonna sound stupid, but how would I go about asking for his contact info so we can be friends?

Give me a shortened version of the text
<bot>: Share the same taste in humor/movies/music as my grocery store cashier. Would like to be friends, but not romantically. What do?
