I was waiting to see a specialist at the hospital, and I had been in line for an hour, with twenty people ahead of me.

Suddenly, someone patted my shoulder: "Brother, 200 yuan, I'll swap places with you."
I said no. He increased the price to 500.
I said no. He said 1,000.
I stood up and left, giving him my spot.
I went to the back of the line and queued again for ten minutes, and the previous spot was called.
He went in, and after three minutes, he came out.
