He Never complained. It doesn't say he complained. It just says he doesn't always want to have all the attention and he wanted to go sight seeing.
I have read every interview and he has never complained in any of them. Many times he talks about being greatful or lately about his cats ;)
And come on, everyone has a bad day. Money doesn't mean everyday for the rest of your life is going to be the "bestest day ever"
And also I might point out he was out having fun (not being upset and complaining) and he signed a ton of autographs for fans. So why would you say his complaining is annoying.
