Yep. Here's how it would go down:
JUDGE: "Kromanm, did you pay for the knife and do you have proof?
KROMANM: "Yes, your Honor"
JUDGE: "Kromanm, did you receive the knife you paid for?"
KROMANM: "No, your honor, I did not."
JUDGE: "TT, did you receive payment in full from Kromanm and did you mail the package to him?"
TT: "Yes, your honor."
JUDGE: "TT, do you have any proof of shipping the package to him?"
TT: "No, your honor."
JUDGE: "My ruling is in favor of Kromanm. TT, pay Kromanm in full"...judge smacks his gavel....."Next case!".
All done in five minutes.
With that thought in mind I think I have better things to be dwelling on than two grown men unable to work a knife deal out. Do they really want to find a way, I'm not sure?
