tix get transferred on the spot all the time. At the BTT my buddy was camped out at the hotel across the street, and he hired a guy to shag people on the streets to him. The new modern scalping, was pretty fun to watch.Yeah - I've wondered about that too. I suppose tickets can be transferred on the spot but that is a little more clumsy than handing over cash for a paper ticket.
And then, with regard to paper tickets, have to be extremely careful that the seats haven't already been transferred electronically because that voids the ticket barcode for entry.
Probably just better to buy from someone you know and trust if you can. Or, secure broker sites with guarantees - UGH.
