I can only imagine the trail of destruction and carnage that led the Hasegawa homeware store to put this sign up on their front door:
You know roller shoes right? Look like trainers but they've got a hidden wheel in the heel and seven year olds use them to look like they're flying down the street. Every kid I've seen using these things has seemed to be at Olympic proficiency level, tracing effortless circles around their tired looking parents. But I can imagine a lack of concentration; a painstakingly erected pyramid of crystal champagne glasses; a red faced manager; the need for a prohibition sign.
