McDonald's was founded in the 1950s in the USA. It's been almost 70 years since the American giant conquered the taste buds of the greatest number of people around the world. Over the years, the company has of course evolved, whether in its menus or its packaging. If some people are convinced that they know everything about the famous fast-food chain, we bet that this is not the case!

On a regular basis, some well-kept secrets are revealed to the general public. For example, we remember the tips on how to pay less for your menu or the advice of a McDonald's employee. Today, we have made a major discovery. And it's clear, you've been eating your fries the wrong way all along!

We can already see you standing in front of your screen, gawking and wondering how this is possible. Don't worry, we didn't see this revelation coming either.

A handy trick to know

The Twitter account Today Years Old, which is full of fun facts, dropped the bomb. According to them, it's all about the shape of your fries box. Indeed, we are supposed to fold the back of the box outwards. Who knew?

Then put the ketchup, mayonnaise or any other sauce of your choice on top of that little spot. So give up the idea of putting the sauce in the open box of your hamburger like you've always done. Now you know what you're supposed to do!

Although this method can invite certain issues, especially if you're wearing long sleeves. So be sure to not stain your clothes by dipping your sleeve in the sauce...sauce is meant for fries not clothes.
