I have no idea if this applies to Mr Madden, but sometimes when you become wealthy, you expect people to cater to you and the little people don't matter. "Cutting" line to get to the front wouldn't even seem as a faux pas to them. They just expect to be served with priority.
Occasionally I do dumb shit that probably comes off as a jerk move, but it is unintentional ... and I am neither wealthy nor old enough to claim dementia. I try to cut people slack, and even famous people can't be Mr. Nice Guy 100% of every day, even if it seems like that should be their personality.
