The cashier that took our order was a young black female. We ordered three small hamburger combos but she was charging us for the regular size and when we corrected her she gave us a very bad look and attitude. As we're waiting for our burgers to be made we noticed that there were four fries when in fact we only should have gotten three and the cashier had charged for the extra fries. She actually blamed us the customer for making the mistake. To add to this while we were sitting down eating our meal the cashier kept glancing back at us with dirty looks. This type of service is completely unacceptable considering that she is the first point of contact for the business whereas the cooks were the ones that were actually friendly.
