Tracker Bar Philosophy

Just in case you don’t all know (don’t know if they have these in the US or not) a tracker bar is like this bar made of cereal and chocolate and stuff and is a tasty snack food.

On the back of the tracker bar I had the other day it said
“Please return this product if it fails to satisfy.”
I have to ask, firstly, surely I have to eat it to know if it satisfies or not - so what the hell do i return? Secondly, satisfy how? Should I be hacked off if my tax returns for the coming year don’t mysteriously complete themselves? Or should I be expecting some form of cereal and chocolate bar based Nirvanic state? They are clearly employing philosophers for this kind of thing.
