There's a lot of kids that aren't like that once they reach, say, toddler age. They know they can terrorize mom/dad as much as they like and they'll still be there, so they ruthlessly exploit that. They can be ruthlessly terrorizing next to their parents, but put them next to a stranger they'll be polite and relatively quiet because they intuitively know they are capable of anything.

i.e. when my child was young, a waiter could hand them a lemonade and they'd be ecstatic. If I handed them the same lemonade, they would start screaming at me the color of cup was wrong.

Agreed. The point of these things is that the company is betting on you doing the decent thing at your expense. I refuse to accommodate their failure.

I was in one of these situations once where we missed a scheduled flight because of an airline screwup, and they refused to accommodate us without a substantial payment - thousands of dollars. Frankly, I couldn’t afford it. This despite the fact I already paid for an assigned seat on the fubar flight.

The predictable outcome happened after they pulled away from the gate and the flight crew came to me and my response was “He’s 20 rows away, what do you expect me to do? Sounds like the options are to move us, or return to the gate.”

They figured it out and were great about it, but the whole situation was stressful to everyone and was completely unnecessary. Flight crews are busy and it’s just senseless toil.
