Eagle-eyed McDonald’s customers have noticed something strange about the lids of the drinks, and it’s seriously baffled them for a long time.
If you’ve ever spent time idly looking around whilst in your local McDonald’s restaurant, your eyes may have been drawn to the top of your drink as you devour your chicken nuggets, Big Mac or McPlant. And, on the lid of your milkshake, or Coke, you would’ve noticed some raised bumps on top, which may or may not have been pushed in.
The buttons on the lids of drinks have baffled some diners, but now McDonald’s workers have confirmed what the bumpy lids mean. And, it’s all to do with staff being able to tell the difference between different drinks, the Mirror reported.
