No amount of telling me that you left your coupon at home is going to move me enough to want to give you one.
I’m a cashier, and my heart is a black and icy pit of I Don’t Really Care.
STOP glaring at me because I am recounting your money. You saying “This is twelve” is NOT any kind of confirmation, especially if you hand me a pile of mostly singles. I’m not only making sure you didn’t hand me under your total, I’m making sure you didn’t give me too much. I’m not saying you’re lying by counting again, it just happens to be my job to make sure for your sake and mine. K? Cool. Thanks.
