Okay, so this is my story:

I go to Wendys and give them the coupon. The guy looks at me and says, no we're not participating. I said ask your manager, he walked and manager said: "He 'carved' that up in Photoshoot, we don't participate".

Then went to Dunkin Donuts:

I gave the coupon to the lady and said, here, for a dozen donuts. She said, "We don't participate". I said, "The coupon clearly says 'Valid at any Dunkin Donuts in North America'". She says: "Yes! North America!!!!! Not Here". I said" Wait a minute, WTF, we are in the United States, which is in NORTH America..." She says: "No, North America is NORTH of us". I said: "You idiot, that is Canada". She says: "Fine, Give them a dozen donuts and put up a sign that we don't accept coupons that is eligible for NORTH America".
