From the #McDonalds Facebook page:
Somehow this doesn't inspire confidence, especially if you have young children or elderly family members affected. And their, "We're sorry" comes off as being a little trite as if the company is a naughty toddler caught stealing from the cookie jar, confronted and made to apologize after standing in the corner for 5 minutes.
