He thought I was a kid; not an Heating and A/C serviceman.

It was my first time out without a instructor, and I was petrified, but i thought it was difficult working on an Heating and A/C system with the instructor, however this was even scarier. I was afraid I would make a mistake, and there would be no one there to point out what I had missed. I thought I had messed up because his eyeah were trained on my every movement. Walking up to the door was frightening. I had my current uniform on, and my ID badge was pinned to the pocket. I rang the doorbell, and waited for the customer to come to the door. When he opened the door, he started to shut it again. I cleared my throat and asked if he had called for an Heating and A/C serviceman; He said he had and told me he thought I was a kid selling something for school. I took a deep breath and smiled; After bolstering my courage, I told him I was the Heating and A/C serviceman and pointed to my badge. He invited me in and told me what was happening with his air conditioner unit. He showed me where it was, and I went to work. Halfway through my inspection, I realized I didn’t have the part I needed to make the repair. I apologized for my mistake, although he didn’t mind. He was glad to find out what was wrong with the A/C unit, and asked when I would return. I told him it would be less than an hour, and I was right. I returned with the part, and suddenly repaired the air conditioner unit. He offered me an excellent review on our website.
