["I had a doctor's appointment last week and had to wait over an hour to see him."]
I bet you were very annoyed
I had a doctor's appointment recently and intentionally scheduled it as the first one of the day so I didn't risk him getting held up with another patient. I got there early - actually had to wait for the receptionist to get her coffee. After all that, I was put out when the doctor showed up over an hour later. He decided to have breakfast with his son!
