Our worst was probably on our last trip, when we went to Pizza Planet. Now, let me say up front, I went in with less than high expectations, but they rest of my family really wanted to try it. When DH turned around with the food, I noticed that over half of our order was missing, including all desserts. He told me the person filling the order said that was all that we had ordered. We were still in the area to pick up the food, so I walked him (and the three kids) back up to the pick up counter with the receipt. It took at least 5 minutes before anyone acknowledged we were standing there, and then they didn't see any difference in what they had given us & what was on the ticket. We finally got the person to bring the rest of the food up.
