Ordered two 44 strawberry fruit slush and one corn dog.  Gave 5.39, bill was 3.39 and Serena tries to give me $1.00 and change back and two 32 oz drinks.  :-(\nI brought change to her attention and had to check size on cup.\nOn a more recent trip through the drive through I again had a similar experience in which the cashier at the window did not give me all my change.  \nI'm not tipping a buck to these people when I come through the drive through.  Seriously, this is ridiculous that they even attempt to pull off this little maneuver.
