Denver Men, how should we hit on you?

So a lot of you commented on this post from a couple days ago:
https://www.reddit.com/r/Denver/comments/1i8xmz5/where_to_meet_single_guys/

Now that us 30-something ladies know where to meet single guys our age, my question is: What should we say if we're interested in you?

Being completely serious. This morning I sat next to a cute guy at the coffee shop and would have loved to ask for his number, but didn't want to be a creep.

Help me, I hate the apps! (and please don't be gross)
