3 things Tony Stark had to pay for (and five he didn't)
1. The TiVo (and the living room, and the hallway, and the 3rd floor bathroom)
Tony Stark was a rich man. A dirty rich man. A "my socks cost more money than you see in a year" man.
The Avengers, it seemed, were trying their damndest to change that.
He was alright with paying for the Avengers tech out of his own pocket. Hell, he built most of it (except for the bathrooms in the Quinjet- those were added by a plumber named Gary after a disastrous night of bad schwarma). He was even alright with paying for a super soldier, an Asgardian and an angry green giant to eat.
He was not alright with paying for a new pair of XXXXXXXL purple pants every other week (and the Hulk would not wear any other colour). He was not alright with paying for Thor's hair products. And he was not alright with paying for technology that Steve broke.
Steve meant well enough. He just could not understand how to operate anything that was not used for super-heroeing. Even Thor could use the stereo better than Steve. Steve's worst operating skills involved Tony's other baby- his 75 inch ultra-high definition super plasma 3D TV with full surround sound. Tony had installed a TiVo onto his baby, because the team was never around to watch their shows when they came on.
He really should have ordered Steve not to touch it.
Steve had turning the TiVo on and off down pat. That was not a problem. He was just wasn't good with any of the other buttons.
Tony wound up paying for a new TiVo (because Hulk threw it at Steve, missed, and sent it flying out the window) new living room, hallway and bathroom when Steve managed to delete every single recorded show. Most Avengers were just annoyed, but the Hulk was livid about missing the Gossip Girl season finale.
15 minutes later, Hulk had managed to destroy the room the TiVo was in, the hallway adjacent to it, and the bathroom across from it. He finally calmed down when Clint explained that he could download it and they could watch it on another TV. Miraculously, Tony's beautiful TV remained intact.
Tony didn't have to pay for the My Little Pony box set Steve bought for him to make up for the deletion of at least 10 episodes. He also didn't have to pay Steve to remain silent about Tony watching a children's show about talking ponies.
