Just as a side node. The usage of this example is a little unlucky
because it has so many traps based on cultural differences. I saw that
discussion coming when I read it.

In Germany on food products you will find the word "Expiration Date"
which literally means: "Don't eat me after that date." But there is a
discussion to change that because what they are actually meaning in this
context is: "I won't change my shape, taste and rigidity till that
date." So I guess, people with such a background are a little more open
to the interpretation of that phrase.
But as far as I know, in the US it says "Best before" to avoid that
confusion and make clear that this product is probably still good, some
time after that date.

And I think the same confusion is going on with respect to the
expiration date in our context. And I am all for not overloading the
meaning of words, so if I read expiration date than for me this is a
dead line. If you mean "best before" than I would prefer if people say
it like this.
