Fast food lovers have been left baffled after a McDonald's worker revealed there are actually two different types of eggs used in restaurants - and they're not all fresh.
The worker, from the United States, gave an insight into the behind-the-scenes in McDonald's kitchens across the pond, as he made both folded eggs and round eggs.
"So I'm gonna show you the difference between our folded egg and our round egg. Folded egg come pre-cooked, they're not this yellow in real life, I don't know why they're this yellow in my camera," he said, in a clip posted to the @essentialsmcdonalds TikTok account, the Daily Star reports.
