I have a dumb cashier story

This morning, at 10:30, I stopped at BK and got a double hamburger and drink. She tells me that the burger is $2.21 plus the drink. I stop and think and say cancel that and I want a double cheese burger hold the cheese. Now that burger costs me $1.00 plus the drink. You have to outwit these people, they are not there to think for you.
