Work with customer

Sometimes we complain about how we had been served. There are many reason for make complain. Some people did not like how they were cared or they did not like the food, in case of a restaurant. In that case we can complain, but other screaming people complain for stupid things. Many times the people that deal directly with the customer have to face this kind of people, the complaining costumer. Some situation are very difficult to handle, for instance, if a customer order a little steak cooked and you make the food, but he does not like and he want it less cooked, for the next hour he order to you make the order again three times. The last time you personally take to his table a steak directly from the freezer. I know how that feels because I worked with customer during one year.
