Dude probably could have recovered a portion if he didn't try to strong-arm the guy infront of other people.
"Please"
"Finders Fee"
"How can we work this out"
I didn't see any of those approaches.
Edit: I did see a lot of
"Theif"
"Calling the Police"
"Felony charges".
When dude tried strong-arming infront of others, other dude naturally felt compelled not to appear 'weak'.
