I posted about this before....
This happened to me when I was in Amsterdam.....I was walking a dude on a bike dropped his wallet literally right in front of me and a couple of people saw so I instinctively picked it up and ran after him but he had his head phones on....I chased him for a good block before he was outtie.....when I realized I wasn't going to catch up to him I kept going looking like I was still trying cause folks were looking at me....
I made an honest effort and I was still looking to give it back so I looked in and there wasn't any ID with an address just cards to random stores and shyt but there was like $200 in both American and Euros...
So I did what any logical person would do and treated myself to a burger and a whore that night
