You lot called him a con atrist, pretty much. He has come back being a seeming to be decent guy trying to justify himself (albeit it's not perfect but its first time he has done thing and maybe lessons will be learned).
Just give the lad a break and appreciate the fact that it's not a huge money making scam like you first winged about!!
EDIT: It's also just the fact that you can see he has spent all night putting that together, then you lot pipe up and go in so many words "oh well, check the nick of your expenses," Fuck me.
I mean, not even an acknowledgement, or like, "Fair enough pal, we see where you are coming from, BUT..."
