The customers of MC Donalds have recently discovered the purpose of the buttons and bumps on beverage caps and are delighted with this discovery.
A video shared on the Today Years Old Twitter account shows someone demonstrating how to press the buttons surrounding the straw on the lid of a drink from the fastfood chain.
Did you notice the drink lid? Not only does it accommodate the straw, but it also has features different from other lids that serve to identify the type of drink in the glass. If you haven’t noticed the rectangular shape, now you’ll understand the real reason!

Although many comments indicated that some people already knew the purpose of these circles, there was great surprise when they learned what the rectangular circles are for.
Many customers correctly concluded that the round knobs act as visual indicators to identify the beverage contained in the glass. We’re sure you don’t know the right answer either.
Each round button on the beverage lid has a specific label, such as “diet”, “cola”, “RB” for root beer and “other”. The function of the smaller rectangular buttons next to the round buttons wasn’t that obvious. These rectangular bumps are used to correct mistakes when an employee presses the wrong circular button while preparing the drink.
Of course, the round buttons serve to identify what kind of drink the employees have poured into the cup. For example, if they accidentally hit the RB button instead of the Diet button, they can simply click the button next to the RB button to reset the lid and correct the mistake.
Yes, we are stunned here too! Did you know about this communication impairment that the cap can detect?
