Everyone knows what classic McDonald's fries are like, and that their only use is to contain the fast food company's product. But recently a Twitter user posted a photo that would be the box's best kept secret.
According to the user, the larger flap of the box has the function of becoming a base to place the sauces that accompany the product. Only the rear cover of the container should be folded back to provide greater comfort to users.

"Did you know that the flap of the potato chips has a purpose?" Can be read in the publication.
Several users responded to this tweet with jokes and disbelief. Even one of them said that McDonald's should thank him for the free promotion, since in the United States, at the end of the month, the network will launch a new line of potatoes.
