Mild face punch, but for a reason I haven't seen anyone focus on yet: lack of planning!
An enormous part of being a Mustachian is looking into the future, gathering all available information, and taking it into account when making decisions.
For a $25 concert, the parking information was surely published online, so it should not have been a surprise to you. And you should have been aware of your transportation costs before you made the decision to go, not once you were already there.
Refusing to fall for bait-and-switch tactics is a good instinct to have, but this was a bait-and-switch situation only because you made it one. So, face-punch for wasting $6, a bunch of time, and warming the globe for no reason at all.
I go to lots of concerts, and finding the cheapest ways to get tickets, get there, and park are a huge part of my decision-making process. Sometimes it will be worth it to travel to the box office beforehand to avoid fees, and sometimes it's better to just pay the fees. And there are certainly times where the parking situation at a venue is the tipping point for me deciding not to go. But I make that decision before I go!
Other tricks for the Mustachian concertgoer are to not buy drinks, and to keep your ear to the underground so that you can catch the awesome upstarts in an intimate venue for $10, rather than seeing them with 2000 other people when they're fat and lazy and charging $40.
