I've taken an online survey given by Starbucks via random receipt printouts and several of the questions directly ask if you were greeted, asked to purchase additional items, ect. So from the sound of it, they're doing their job correctly at your local shop.
FWIW they have my drinks ready and muffins for the kids and even know how the order varies depending on whether it's a weekday or weekend.
Of course that's not as bad as having your voice recognized over the Burger King drive-thru speaker
