Free Slurpee Day!

Because today is July 11th, which is 7/11 shorthand, 7-11 is giving away free Slurpees all day!

UPDATE: I visited my local 7-11 and asked if today was free slurpee day. The woman looked at the clock on the wall and said, "Yes, but it ended one hour ago." I asked her what time it ended and she said, "It ended" and walked away.

Does anyone know to whom I can address my complaint? Clearly it is still July 11th and nowhere that I've seen on the 'net does it say that the freebie expires at a certain time of the day. I think she lied to me. I think I'm not going back there anymore!
