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.
UPDATE: 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.
