I would rather try to hang out with the guy and see what I could learn by watching/asking questions.

I've only been playing for around 4 years.. and since I have no idea how to "teach," when i try to show a friend how to play it becomes a disaster. Not worth $1. Maybe he's Jimi, maybe he can teach well, then it'd be worth it.

If you know absolutely nothing about guitar, you're probably better off getting one (if you dont' already have one) and becoming familiar with it (if you're not already) before you set up appointments with a guy and spend 20 dollars on having him show you a couple of chords. You can do that with chord charts and tabs all over the internet.. for free. Well, this is what I did.

I got a guitar one Christmas & let it sit there until the following summer. One day, I got tired of looking at it so I picked it up and beat on it almost every night. Soon I was playing only intros to my favorite songs, and while it was annoying to my friends, it motivated me to learn more.
