This video is very short (just 12-seconds long) and very simple (it’s basically a guy standing still). Yet it manages to be both educational and funny at the same time.
The only question I have after watching it is: Lazy or genius?
I think the guy is a genius, personally. He’s taken an objective look at his job and worked out how to make his life easier and how to use his time more efficiently.
Unfortunately I suspect his bosses wouldn’t be too happy to see how he cleans the glass alongside these moving sidewalks. They’d suggest he’s being lazy and shirking his responsibilities. Which is obviously codswallop, but then bosses aren’t always right, no matter what they might say.
