Understand people who have crappy jobs.

• The TSA officer does not want to pat you down.
• The IRS agent does not want to audit you.
• The CVS employee does not want to ask you to pick up your dog.

People who have crappy jobs are not trying to piss you off. They just want to keep their job.

Expressly noting you’re helping them keep their job (not get in trouble) helps everyone in the game.
