Those stars would be -10, This taco bell definately has a scam going on with giving back your change. Also does taco bell donate rounded up totals to schools????? I would HIGHLY RECOMEND COUNTING YOUR CHANGE in front of them so they CLEARLY see THEY made a mistake with your full amount of change and you did not magically hide what is owed back, but then again even when you prove that you dont have whats owed....they still dont wanna give you correct amount....until they realize your willing to take it the whooole way....
