My plumber came to fix some plumbing. As usual, he's bringing his big bucket, full of tools. An ordinary plastic bucket.
When questioned about it, he said: "Oh, I bought about every kind of toolbox and organizer on the market. They don't do the job: too many pockets and compartments. I keep this bucket to go in clients' house, and keep a big hockey bag in the car, for the big tools."
Sometimes, when one needs a big bucket and a big bag, one could just pick a big bucket and a big bag.
