Bumped Off

Recently I was on a flight, I was scheduled to fly at a certain time. I arrived at the airport on time. I registered and gotten my ticket and my boarding pass. Everything was according to plan. But for whatever reason, everyone had gotten on the plane except me. They said they didn’t have a seat for me. I couldn’t understand what had happened. I calmly approached the desk and asked the stewardess, “What about my seat? I have not been assigned a seat?”
