Jackets are srs business, especially to some people, especially when new. Dude puked up on my jacket once, he didn't even offer me money for the dry cleaning. I didn't even get to hit the bastard neither! Well, I did, but he was so fucked it would have just been hollow. True Story.
If I lost me a jacket that I cared enough about to get back, well, I'd go and get that mother back! Admittedly if I was in the possession of another jacket, I wouldn't give it back til I got mine back, not devious but just how I'd roll with it, who knows if I *would* get my jacket back, might as well get something out of it, ESPECIALLY if some other dickhead left with my jacket(actually happened to me once with some coats, never got mine back either). As for what you've done wrong...hmm, I'm not sure, I need to put myself in this situation a bit more first, one bit of your story totally confused which jacket was which and it totally fucked me over in my thinking cos I spent the rest trying to figure out what was what?
