As mentioned, scalped tickets, while not the most ethical thing, at least put the listed amount of money into the hands of the artist and incur a financial risk to the scalper. This potentially ties up a bunch of tables that may never earn any income and if I was a restaurant finding myself on this service I would be pretty ticked. The number of people who know to look here for a reservation is minute, let alone willing to pay for that reservation. I'm betting that a high number of those tables sat empty tonight and those restaurants are already out money.
Additionally if the restaurant has done all the work to create such a high demand for their seating, they should be the ones pocketing the profit off of it.
At the end he asks to work with this industry but has already begun screwing them. I'm thinking not the best method to foster co-operation.
