text: I usually don't write reviews for huge chains like this, but sometimes you just gotta vent.  Hit the drive-thru on Black Friday with the wife.  I ordered a Venti (large) caramel brulee latte, while she got a Tall (small) Pep Mocha latte.  The total was approximately $8.  I roll up to the window, and hand the cashier a $5 plus a coupon for one free drink.  I'd assume that she'd take off the most expensive one, or at least ask, but no, she didn't ask.  So I was expecting about $1 plus change, and was surprised when the cashier gave me $.18.  I questioned which drink she took off, wondering why the venti wasn't the free drink.  Her rational to me was that 'it wasn't that big of a difference because both drinks are about $4'.  I questioned her, specifically asking her if venti and tall drinks really cost the same.  She insisted that yes they did.  Of course, she proceeded to hand me the receipt, I saw that was false (which I already knew).  Yes, it was only a dollar, but this was a complete and utter customer service failure.  If I had not said anything, I could understand, but I questioned which drink she took off and she either lied to me, or was too incompetent to know the price difference.  Additionally, annoying is that I promptly sent an email to Starbucks customer service and a full week later, I have not received a response.  Zero stars to this location and zero stars for no email response from Starbucks corporate.\n\nUPDATE:  I'm upgrading this location to a half of a star.  Starbucks corporate finally contacted me about my letter about 10 days or so after I sent it.  While the email they sent me was apologetic, they did not answer any of my questions about Starbucks policy.  Lame.
