Mcdonalds plastic soft drink lids have four sets of bumps you can push in to identify the These are labeled Other Diet Tea and P What heck is for?

You're right! Those bumps on McDonald's lids are for drink identification. Here's what they stand for:

* O: Other (this usually means a drink that doesn't fit into the other categories, like a milkshake or iced coffee)

* D: Diet

* T: Tea

* P: Regular Soda (or "Pop" as it's sometimes called)

So, the "P" bump is for regular sodas like Coke, Sprite, and Dr. Pepper.
