I’ve shown up to venues before and paid less for a ticket from the scalpers than if I would have walked over to the box office because they were just trying to unload them.

I’ve also sold an extra ticket for a friend by just walking up to a random person standing in the ticket line and offering it to them for face value (which saved them money on the ticket counter markup).

Both cases involved turning what would have been a complete loss into less than a complete loss. Never felt bad about the scalpers loosing money because they knew the risks and my friend was just going to eat the loss because whoever the ticket was for couldn’t make the show for whatever reason and I was like “I’ll get rid of it for you”.
