I've never consistently received bad customer service from a place.
I went there on 12/11 at 8am and ordered a large iced white chocolate mocha. There was no one else in the store. The three workers there literally just walked around for 15 minutes doing nothing, until I got up and asked for my coffee. The lady replied that she forgot.
...but I'm the only one in the store. She makes it, then forgets to put white chocolate mocha in it. Then she says she forgot and thought I just ordered a coffee. The level of sheer Incompetence I just witnessed forced me to write a review. Awful.
