“Great burgers and rude service” is the concept behind the Australian burger chain Karen’s Diner — according to its website. Insider spoke to Chelsea, an employee at Karen’s Diner in the UK, about what it’s like to swear and shout at customers for a living. Chelsea said that her interactions with customers are regularly posted to TikTok — and that the social media platform is the company's greatest asset, with some customer-posted videos garnering millions of views on the app. Getting into the Karen character involves reversing “everything that you’ve previously been taught” in previous jobs, Chelsea said. But when you get the hang of it, she said, it’s easier than it seems and actually makes her job more enjoyable. “You just get everything that’s bothered you out on that shift. It just comes straight out of your mouth. So if a customer’s getting on your nerves, you just tell them to shut up, and get on with it,” she said. Click the link in our bio to read more.
