Not the one you asked, but I have a similar attitude, and some sense of trust and fairness is necessary to maintain this attitude.

If I'm in urgent care for a relatively non-serious problem, and people who much more urgently need care keep getting served ahead of me, that just seems like the right way to do things, and I'll be happy to wait my turn, or eventually give up and go home.

On the other hand, in line to pay for purchases I would not like for someone to cut in front of me. It's rude, and there is an established norm that they would be selfishly breaking.
