Life's random funny moments

hi Kcash well this started out not to be funny then afterwards when I thought about it I had to laugh, I watched as the grocery checker added up all my food items and asked for twenty five dollars so I gave her two twenties, forty dollars in other words, and should have got back fifteen dollars but she hands me two twenties, and I say you gave me back too much money, and she screamed at me I never make an error, take it, and move on. I again said You should only give me fifteen, and she again more loudly, with a dozen people backed up all glaring at me, I never make a mistake and whammed the money into my hand so I go off with forty dollars and my groceries then i sit down in my friends car and tell her what happened and we both start to laugh, so whenever I hear someone say I never make a mistake I think of that and laugh like crazy. forty dollars and twenty five dollars worth of food.
