Brought my daughter to petco to pick up some new fish with her birthday money. She handed the cashier an older but crisp and perfect condition 100$ bill . THE CASHIER WOULD NOT ACCEPT IT DO TO IT BEING AN "OLDER" BILL AND NOT HAVING A STRIP THAT SHINES IN A FLORENCE LIGHT . User's recommendation: Find another per shop that will gladly accept legal tender. Do not cave to these moronic cashless society businesses.
