Free Banana

We stopped for gas; the mini-mart
Was advertising wares.
I wasn’t hungry, had no thirst
And so I thought, who cares?

But then a sign jumped out at me;
I wondered – is it true?
Just buy this brand of water
And we’ve got a gift for you –

A free banana! I said, Huh?
This seems a bit surreal.
But hey, I guess, to some at least,
There must be some appeal!
