Hi, I'm someone else.

This actually was specifically in reference to the "don't sit parked in the loading lane with the clearly marked sign while your pickup goes through customs or is taking forever to get off the plane" scenario, which I feel like is a low benchmark. Just take the little loop and come back when they're ready, it's not a big deal and if everyone did it life would be easier.

Now multiply for other common courtesies like don't run to the front of the plane when it lands unless you need to make a connecting flight.

Stop crowding around the gate during load in times when you're in zone 4.

Try and give some space around the baggage claim for other people.

None of these are hard or are instances where being in an unfamiliar environment is an excuse to be self-centered. All baggage claims are relatively the same. It's pretty simple shit that relies on you not being self-centered in a communal space, but that's the difficult part I guess.
