Yes, we do.
Here's what it looks like:
Three different kinds of cereals. In their decanters.
Yup, that's part of putting the groceries away. Milk on the refrigerator shelf. Bread in the bread-box. Bananas on the banana hammock.
And cereals, of course, decanted. And the empty boxes discarded.
It seems that most people don't decant their cereals, so we sometimes get asked why we do.
The answer is: For the same reason we don't get broadcast or cable TV; to shield us from advertising. There's too much advertising on a cereal box.
Some people object to unsolicited messages in their e-mail, and resort to counter-measures to minimize that nuisance. Some object to pop-up ads in their browser, and resort to counter-measures to minimize that nuisance. We do those things. But there are also unsolicited commercial messages broadcast on television, and printed on cereal boxes. We take counter-measures against those, too.
