"We are really trying to like this place but they continue to have service problems. They brought out the food for members of our party, but the last order didn't make it out until the rest of us were almost done. Clearly they had forgotten to start the pizza, and the waiter and the kitchen staff started blaming each other. Admit you made a mistake, say you're sorry, offer some sort of recompense and move on, but don't start making excuses."
