Just How Much Was That Coffee?

Washington Nationals pitcher Doug Fister creatively embraced the Christmas spirit. On Christmas Eve, Fister posted a barcode on his Twitter page offering his followers a free cup of coffee from Starbucks--his treat.  He also requested that people not rob from Santa's Sleigh, so to speak, and use the barcode only once.  Fister earned $7.2 million in 2014 with Washington.  He also has over 24,000 twitter followers.  There's no word on how many drinks ended up on his bill.
