Think you're potentially missing the point here.
I waited in the queue for 7 hours, looking for £150 tickets. When I eventually got to the front, the exact same ticket had been hiked up to £350.
I chose not to buy it.
At least half a dozen people I know experienced the exact same thing.
Had I known they were £350 from the off, I wouldn't have wasted 7 hours in the queue, because I know £350 is not a price I'd be willing to pay.
Other industries like airlines and trains, even Uber have "dynamic" pricing, and everyone accepts and understands that.
Clearly a train to London that gets you there for 8.30am on a Monday morning is going to be priced higher than a 2pm train on a Tuesday afternoon, because the demand is so much higher.
Everyone understands that, and accepts it.
As a consumer you have a choice - pay a premium for the most in demand time slot, or pay a cheaper price to go off peak.
You know the price you're being asked to pay before you get in the queue.
The difference with these gig tickets was, it was done under false pretence.
The overwhelming majority of people (including all the people I know who experienced it) had no clue the price would be more than doubled by the time they got to the front of the queue to buy.
It was underhand and exploitative.
And the difference with peak and off peak trains is, they're different services, offering different benefits. There's a premium attached to the more attractive service. There's consumer choice.
With the standing tickets, whether £150 or £350, they are the exact same service. There is no consumer choice. Those who chose not to buy are not consumers.
In one word - THIS!!!!!!
