I’m chatting with the barista. He tells me my order will be up soon. I ask him, “Did you ring me up?”

He’s completely confused.

I straighten it out, explaining that I wanted to know if he’d charged me, and walk away, laughing. It used to be — a classic beginning to an explanation about change — that cash registers made a ringing sound when transactions were totaled for payment. How long has it been since I’ve heard a cash register ring? As a result, ‘ring me up’ entered society as a popular expression for paying for purchases.

As an aside, my wife had one of those mechanical, ringing registers in her house. Her father, a grocery store manager, procured it when his store upgraded to an electronic system. The register’s ring reminded him of the little stores where they’d shop in his small town.

He said that he never wanted to forget them.
