A checkoutbot is a humanoid appearing object behind a counter at a checkout register that appears to be human but in fact is so heavily controlled by regulations and policies it is in fact no longer capable of acting like a human being and for all intents and purposes is nothing but a mindless robot.
I got a 1$ extrabucks coupon at CVS yesterday and tried to buy a bottle of seasoning with it, but the checkoutbot at the counter said the coupon wads for 1$ and the seasoning was "Only 99 cents" so it would not let me use the coupon when I refused to buy anything more. So I could not make a 99 cent purchase with a 1$ coupon because the checkoutbot was so devoid of human logic and reasoning it was incapable of taking any intelligent action.
