I learned years ago while working computer support in school that no one enjoys receiving a superior attitude. Questions are always handled compassionately.
Growing up on the farm, I learned at an early age that the job just needs to be done, since no one else was going to do it. I have maintained this work ethic all of my life.
In my past career, I have learned that an employer invests significant resource in training an employee. Therefore, I tend to choose work carefully, and remain in a position for many years.
