Free coffee for National Coffee Day roundup --- National Coffee Break!

You've probably seen some posts about National Coffee Day tomorrow, September 29.  Check out this article for a round up of the places offering free coffee for a National Coffee Break.  If you know of anywhere else that's hosting free coffee for their customers, please leave a comment.  I haven't been able to find confirmation that Dunkin Donuts is offering coffee at a discount yet.  I tried to call a local DD yesterday and they said they're often notified the day before an event and hadn't been informed of any specials for Thursday at that time.
