Some people may argue that a free drink is worth any price but I have to disagree. This is the closest, free standing SB drive throuhg to my apartment and I normally utilize the drive through. I don't understand why you can't get a better menu at the drive. Maybe your die hard regulars remember this kind of stuff but I don't always remember all the items available to order. And the drive through menu is more likely to sell you on food instead than on coffee drinks.
Over the past year I mostly go to SB once or twice a month at best. In that time frame I have had at least 7 Complimentary drinks through the drive though because of the time it took to prepare them. Some people say "hey, free drink" but when you spend 20 min in the drive through (I know I gauged my time through Kelly Clarkson songs) you start to wish you had the option to drive, far far away from the drive through.
I do give many cust service points to SB for the on the house frappachino when I finally got to the window but why does this always have to happen! You are always quick to give me a free coffee when my wait gets long but who wants to sit for 15-20 min over an iced coffee? Maybe you should take a look at your business model and figure out why I have had 7 free drinks in a year due to bad service at this location?
