All you have to do is log into your Starbucks account and hit your green e-gift button and your friend will receive a link o redeem a  5$ gift card , to get a grande pumpkin spice latte. They just open up the link and they can scan the barcode right from your phone. So you can tweet a coffee to anyone your neighbor your teacher, maybe a friend or someone who just could use a cup of coffee.
