As I understand it, one change is that (unlike paper tickets), etickets can't be used for another event. Also an event can have tickets sold or even oversold at the table.
Here is the specific case I've asked about but haven't gotten an answer.
1) Player buys ticket with special fee of $xx. This is the amount over the base price that would normally go back to GM.
2) Player does not make it to event and did not get a refund in time (maybe he couldn't go at very last minute)
3) GM scans all badges, but of course can't scan that player's badge
4) Gen Con collected $xx for that GM's event and currently has that money
Shouldn't the GM get that $xx back as if the player attended? It wasn't the GM's fault the player didn't attend and the money is in the bank. Gen Con really didn't do anything to earn the $xx (which is above the $2/2 hour Gen Con base fee which I'd say they did earn - after all a lot of events don't even have extra fees).
Analogous to buying a ticket for a concert and not making it. The performer still gets their talent fee.
Looking for definitive answer. Thanks!
