When Hugo collided with the man, the journal wasn't the only thing to become acquainted with the ground. A container slipped out of the Weasley's grip and met the same fate. Most, but not all, of its contents spilled on the ground. Luckily they fell on the drier part, but he wasn't thinking about that when he rounded on the bloke, temper flaring.
"Bloody hell, can't you see I had my hands full?" Hugo groaned, ignoring the fact that it was partially his own fault. He had had his arms full and vision impaired by an icebox filled with raw steaks. But what was this chump's excuse? There was no one else in the way.
