Why do people use hand sanitizer after dumping their dishes on the loading tray? Aren't they the only ones who've handled their dishes? Weren't they clean to begin with?
Why do people brush their teeth -before- breakfast? Isn't it a little repetitious to brush your teeth after dinner and then again when you wake up, when you probably didn't eat in between? Wouldn't it make more sense to brush your teeth -after- breakfast? Isn't the point of brushing your teeth to remove the food left on after a meal, to prevent the chance of plaque buildup?
