why...once you sell me the ticket, it is mine....I can give it away, tear it up, put it in my pocket and forget it forever, or SELL it....the results are the same for the issuer....either someone is in the seat, or not...whatever,they have their admission money.
The issuer isn’t motivated by pure financial concerns, is the apt retort to this arrant nonsense. He really does not want to put on a concert to empty seats.
