Sssshhhh, or you'll come up with another very real factor: the utter inability of people to accept the slightest compromise on anything. Quality, nope. Price, nope. Even just taking the delivery person's job into account a bit, nope.

Perhaps I should stop being surprised when hearing about people going into the emergency room because they have a scratch on their leg, then yelling and even attacking medical personnel to the point they get arrested when prompt treatment is not provided.

And then apply that attitude to actual people. Needless to say, they complain about that too, yet do nothing.
