The name "Karen" has become synonymous with a certain kind of entitled restaurant/retail customer. Naturally, nobody is more familiar with "Karens" than people who work in the service industry, especially if they're the manager. So someone asked managers of Reddit: "What is a Karen experience like ? What was your worst experience?"
1.) From netrunui:
I loved Karens when I was managing. Being able to say "I am the manager" followed soon by "Sorry, that's company policy" always results in a flustered Karen leaving in a huff and a much relieved crew.
2.) From woahhhmom8:
Happened before I became a manager, but once while I was serving at Steak 'n Shake, customer had a coupon for a burger, fries and a shake for $x.xx, can't remember the price anymore. Anyway, on the coupon it specifically stated that cheese on the burger was $0.39 up charge, although it did have a picture of a burger with cheese on it. Lady THREW A FIT in the dining room that I was treating her unfairly, it was false advertising, etc. etc.
