We have ordered pizza delivery a few times and have eaten at the restaurant a couple times. There often seems to be an issue with the invoice. Finally, we decided to write a review after our most recent issue.
We used a "free delivery" coupon for a pizza delivery. When I looked closely at the invoice, the delivery fee had been charged, then credited and then charged again. Bottom line: I paid a delivery fee.
This stings because I tipped the delivery guy $5 because of the "free delivery" promise.
Be careful and check your invoice closely when patronizing this business!
