The Takeout:

Dear Salty, I was at the coffee shop counter, and the cashier wouldn’t take my order until I took off my AirPod! And it was only in one ear! Am I the asshole here?

Oh, Kevin, you sad, foolish little soul. Where do I even begin? [Takes a deep breath.] I am trying hard here to give you the benefit of the doubt. Perhaps you were in the middle of a very important phone call/podcast/guitar riff that could not be paused for the 30 or so seconds it takes to order a cup of coffee. In which case, you very politely step aside to conclude your business and then order your coffee.

Short version? Respect.
