I drove past a 98 cent store yesterday.
I didn't know that there were 98 cent stores.
I've only seen 99 cent stores.

I wonder if what I saw was the only 98 cent store.
I bet it is, and the owner is a former employee of the 99 cent chain.
He or she got fired, then got pissed about the firing.
In retaliation the 98 cent store was opened.
Maybe not though.
