Me and my girlfriend visit the drive-thru quite regularly and every time the staff are very efficient and very rarely make mistakes. The grounds and seating is all very clean and nicely presented, very rarely you wait for anything unless it's at dinner time. The only slight thing is that the staff are all very young and obviously don't really want to be there. I don't blame them in the slightest, I'd be the same, but sometimes it is a little depressing to see how tired/stressed/unmotivated they all are.
