Imagine Zorro.
All dressed in black. And a cape.
But instead of a sword, he has a dustbuster.
He charges into a place, vacuums up all of the food crumbs and dust and stuff, and then runs away.
Not quite the hero to the people, but still serving a valuable role in the community.
After a few encounters with the military police, Zorro decided to trade his dustbuster in for a sword.
But swords aren’t as good at picking up food crumbs and dust.
Even though you can spear crumpled-up paper and food waste and drop it in a bin.
