She needs to learn patience

It always happened to her (my wife) when we went out for dinner or a meal. We would be there at the restaurant and ordered our food and drinks. Others would come in later than us and while waiting for the food, we noticed that the others received their food first. We were then left waiting for our food, WHICH WE ORDERED EARLIER THAN OTHERS. When that happens, I can see the changes on her face. Told her that it is an opportunity for her to develop patience. Hahaha...unfairness can be turned into an opportunity.
