Cast a Vote, Get a Free Taco at California Tortilla
As far as promotions go, this one is pretty simple: Wear your smug "I Voted" sticker (one that you got at a polling station, not one that you tore off your co-worker's chest in anger) and get a free taco today at California Tortilla.
It's a promotion with a civic mind. Well, to a degree.
According to the "official" rules of the giveaway, you can also just scream, "I love Election Day!" and get your free taco. You can be, in other words, a lazy, undemocratic-minded slug and still get your freebie. That is, if you can get your fat ass off the couch to order it.
