I don't agree that jerks are people who don't care about other people's individual circumstances. Jerks are people who think that everyone else is a jerk, which is how they excuse their behaviour.
It's not that they don't care why the waiter messed up their order, it's that they think the waiter messed up because they're a jerk.
