Louis van Gaal doesn't strike us as being a very patient person.
It was no surprise, therefore, to see him walk off mid-signature when a young fan asked the manager to sign his shirt on Saturday.
Unfortunately for the youngster, his pen ran out of ink at the worst possible time.
And naturally, Van Gaal showed no sympathy whatsoever, simply walking away, leaving a devastated fan in his wake.
It's always best to be prepared, kids...
