This is the norm today. I try to teach my grandchildren that our choices have consequences. Of course, I am alone and everyone else lets them have their way. At McDonalds when they want a hamburger and then as soon as I order they decide they really wanted McNuggets I tell them it is too late. They already made their choice. Grandma, of course, stops the kitchen and has everything changed for the FOUR and FIVE year old ..... and I am a mean old man. And then when the kids meal arrives and they get the girl and boy toy (which they decided on themselves) one them puckers up and wants what the other one has and grandma will go stop the ordering and building orders to have them dig around trying to find what the little darling have finally decided they want. This occurs all the time, not isolated and spills over into everything else. After we buy them a toy and get halfway home grandma turns around and goes and exchanges or buys the one they REALLY wanted.
This guy sounds like he was raised that our choices can be changes at will.
