Those Little Knobs On Grocery Carts Are Our New Best Friend
While the back part is used to support a child that’s sitting in the cart, if you look closely, you’ll notice that there’s a loop or hump at the top. No, this isn’t just meant to be stylish but actually has a pretty logical purpose. It’s meant to elevate bags that might be carrying light or fragile items like bread and eggs that might get crushed by heavier groceries.
Even today, you’ll notice baggers still don’t know about this use! Too bad, because there are so many sad eggs and loaves of bread that get crushed.
