Asked for a large iced coffee with caramel and soy milk. Pretty soon I hear the one guy ask the other one how much soy to add to a large. The other one shrugs, comes over, takes the soy and dumps what's left of the container in the cup of ice. It was quite literally a splash. Hands it back to the first guy and goes back to the drive-thru window. First guy adds the caramel and then fills the rest with coffee and hands it to me. I figured I'd give it a try first and woah- very bitter. I ask the drive-thru guy for more soy and he doesn't say a word, just goes to the back to get a new carton, pours more soy in, and then goes back to the window. Not as bad as the Chandler/I-10 location but not nearly as good as Alma School/Germann. Would be nice if training and customer service were more consistent.
