If you are a human being who has ever traveled on a plane, you have probably experienced flight delay. You wait for hours, you get angry, you call people some words that aren't nice.
Well, even Lionel Messi goes through that.
"Once again waiting inside an airplane to try and leave for our destination. What a disaster the AFA are. My God!"
That is Messi blasting the Argentine Federation for making him wait. You can see in the picture that he's really not happy. This must be a long wait of multiple hours, certainly, and that caused him to lose his temper.
Even Messi gets angry, people. So yeah, please don't make him wait on a plane.
