Drive thru customer service for the most part is terrible. I've tipped the person at the window and received no acknowledgement whatsoever..Tonight I ordered my drink and the person making the drinks must have been new because he completely screwed up my order and it took 15 minutes for him to make it (chai tea latte half Oprah half original!). That's 15 minutes after I've paid... (This is not the first time that this location has made my drink incorrectly) If i didn't have to get my child home I would've gone to my usual Starbucks on Eastern and Russell. At least there they acknowledge when you tip them and they've never screwed up my order...
