<human>: Can you provide a brief overview of the text?

I wear sweats, and usually keep my wallet in my front pocket. Lunch lines were a bit crowded so I guess someone must've seen me take out my wallet to get some money and put it back in, and proceeded to pickpocket me after I placed it back. 

Anyways, I found out it was missing when I got lunch and I was pretty pissed. I put the blame on myself because I knew it was my fault I lost it in the lunch line (assumed it must've dropped). So, I waited a day and hoped a good soul would put it in the lost and found, but didn't. I checked my bank account and noticed a transaction made by a nearby gas station with my card. To speed this story up: I talked to the police and owner of the gas station and managed to get my hands on the surveillance camera and identified the pickpocket. 

My question is, what should I do with him? I don't want to beat him up or anything because I'm a 4.0 student and would rather not have an expulsion or something on my record.
<bot>: Found out who stole my wallet and used around $20 bucks in snacks and drinks, what's the best way to deal with this.
