This sign certainly came to exist after some Karen was late and complained that the bus didn’t wait for her to arrive.

I picked up a package from the post office. They had a sign saying “ring the bell once for service, two or more for a weather report”. I image this has a similar back story.

I don’t get it. Is this a play on whether they report to you or not?

I might have said “two or more to speak with our complaint department.”

Customers only get service if they ring the bell once. If Karen comes and rings the bell ten times, Karen won’t get the service she wants.
