Does anyone know if there is a limitation on number of coins you can use per transaction over the counter before the counter person can legally deny your right to complete the purchase? The cafeteria lady is never nice to me and I thought I'd do my share and I paid for my 225cent lunch in whole with two hundred and twenty five pennies. She gave me a nasty look and told me I can't do that. I told her that's all the money I had today and that each and every penny is a legal tender of the United States of America that is legal for all private and debts. hehehehe y'all should have seen the look on her face.
