Frustration is a very common negative emotional experience at work in a customer setting that may arise in a variety of circumstances usually present when our goals are blocked, you have a certain degree of uncertainty about the causes of the problem, you feel this situation is unfair, and you cannot control stuff. What happens after you feel frustrated, is that you can “drop it,” you can persevere, and what you do in terms of the actions to take may depend on personal and environmental factors.
