Experience on July 13th, noon-ish: upon reading other yelpers' reviews, I should known the drive through is bad. Maybe it was my 38 week prego hormone too. I ordered a large hot coffee, 5 sugar and 5 cream. That was it. The older lady in cashier window told me the MCD app doesn't work which is obviously a lie, because it actually did went through after she scanned. Got my coffee black from window #2. I got back in the drive thru line, cashier lady yelled at me and told me that black coffee was my order. I don't even know what to respond. In silence, she just waked away and got another guy to come tell me to go get my coffee at the next window. I know I wasn't purchasing a bottle of vintage Don Perignon from a club, it was just a 20oz coffee from a drive thru; but after that attitude, I am not going to drink that returned coffee. The hassle is from 20 minutes wasted there I have to hunt down my daily dosage elsewhere. Yuck!
