Expired products.  What do you do???

This happened to me today. Very ironic as a similar story is told in my book, Don't Be a Penguin.  Tell me how you would have handled it.

I went to Cumberland Farms today to buy a diet coke and noticed that all available diet coke's had an expiration date of yesterday, Dec. 10th. I was left with the following options:

1. Still buy it as only one day expired - just life life (Penguin)

2. Buy a different type of soda that is not expired - who can really tell the difference (Penguin)

3. Speak with manager to find a non-expired Diet Coke that you can buy - time for an interaction (Alien)

4. Ask to have all of the expired Diet Coke removed due to health violations - if they say no, call police (crazy person)
