Starbucks has announced that you can get a free cup of brewed coffee on Tuesday JUST FOR VOTING.
Wear your "I VOTED" sticker. Or if you're like me and already voted via absentee ballot (or if you are like some of my other friends and voted early), just go in and tell them so. They will believe you. I have it on good authority it's on the honor system.
But even if you hate coffee, vote anyway. It's one of the "perks" (pun intended) of being an American.
