Friend ruined my concert....

[Kratzer]

Backround: I had bought five tickets for a concert (Del McCoury Band) and put them in my car. The show was at a small venue consisting of probably 30 dinner tables (booths). I was very excited for this show, and my plan was to get there early so I could get a booth right next to stage so we could drink/eat while watching the band mere feet away.

The day of the concert I loaned my car to my friend so he could drive to his house because he had to go to work.

I told him "Lock the car and put the keys inside the house"

Well my friends and I get to my car to get the tickets so that we can get to the show about 30 minutes before the doors open. Only when we get there the doors are locked and the keys are in the ignition. I'm pretty pissed off, becuase my whole plan is ruined, so i call to get a tow truck company to come and get my keys out so I can get the tickets. It takes about an hour, and by the time we get to the show we have the absolute worst seats in the house. I was very disappointed.

It turns out my friend thought I meant "Lock the car with the keys inside" because he's stupid and he thought I had the ability to open locked doors without the key (which sadly, I don't).

The cost of getting my keys out of my car was $50, and of course my friend should pay for that. The problem is that he's extrememly poor, and he has no money. He just got a job, but isnt getting a paycheck for two weeks. Should I demand that he pays me out of his first paycheck, or let him pay me later.

The money isnt an issue with me, it's just the fact that my friend ruined my plan for the concert. I was very pissed that we did not get good seats, so i feel like he should be "punished".

Should I make him pay ASAP, or give him time?

Or should I lock his keys in his car? Both him paying me and me locking his keys in his car would probably give me equal satisfaction.
