The worst that usually happens to me is no one can find my house, I live on one of those streets that's only a block long and hidden between other streets (my street only has ten houses). Once however I ordered a couple pizzas and a dessert of some sort, one of the pizzas had the wrong toppings so he took the food back and said he would bring it back free of charge. Well that's all good except when he brought it back he left the dessert at the restaurant, I didn't complain cause I figured I got the pizza free.
