HOW DO I GIVE MY NUMBER TO THE COFFEE SHOP BARISTA

people, I missed out on dating my 20s. well, most of my 20s. I'm having real problems.
  1. like, just, ask him what's his situation and if he wants to do something sometime?
    I love him. he laughs at my stupid jokes and has great calves. I understand he's paid to laugh at my stupid jokes (but not really, he's a barista! they're grouchy as fuck, right?!) but I make REALLY stupid ones.
  2. halp.
    I've got business cards but I feel like too much of a douchenozzle/Patrick Bateman-esque serial killer handing them out to strangers. but God I love them. but I won't do that to him because they don't even say anything sassy.
  3. plz halp.
