#1 Vince McMahon was furious at Daniel Bryan's costume change
Daniel Bryan once fell foul of the WWE Chairman by not informing him about a change in costume in advance.
Things in WWE have to go exactly a certain way if they are to live up to Vince McMahon's expectations. Most changes in appearances, including hairstyles and clothes, have to be approved by Vince McMahon before they can go ahead.

Unfortunately for Bryan, he didn't take Vince McMahon's permission ahead of changing his usual entrance jacket to a green one, when he was set to face CM Punk in a WWE Championship Match at Money in the Bank 2012.
Vince McMahon was furious with Daniel Bryan and shouted at the referee through his earpiece to get him to take off the jacket. McMahon also shouted at Bryan when the latter got backstage, and the superstar never wore the jacket again on WWE television.
No matter how big a star, Vince McMahon likes to have a final say in their look before they present themselves to the audience. Bryan managed to learn this the hard way.
