I’m not that often in Maccies but I’ve never heard of the flurry machine being broken, I’ve read it’s a US thing due to the maintenance contracts
That said the meme still works in Europe because I’m pretty sure they’re not allowed to call that hydrogenated vegetable oil-filled shite “ice cream” here 😂
Have to say, making beer beef stew is a very old Scottish tradition, and Guinness is definitely one of the worst beers you could use. It’s a stout and too heavy with the beef. An IPA works perfectly though!
Edit - also, modern Scottish trick - add a splash of dry red wine too!
