McDonald's drive-thru AI upgrade is causing chaos, confusion, and viral meltdowns on TikTok after customers report getting cold fries, extra sauces they didn't ask for, and bizarre orders like "two happy meals with a side of existential dread" from the new AI system. The fast-food giant's latest tech rollout was supposed to revolutionize speed, but instead, it's becoming a nightmare for workers and a goldmine for funny fails, with one clip of a customer arguing with the machine about a McFlurry amassing 5 million views overnight. Is this the future of fast food or a recipe for disaster?
