Find number abc

I went to the shop the other day. I was only in there for about 5 minutes and when I came out, there was a damn traffic officer writing a parking ticket for over-running the meter.
So I went up to him and said,
"Come on, how about giving a man a break?"
He ignored me and continued writing the ticket.
So I called him a pencil-necked Nazi. He glared at me and started writing another ticket for also having parked partially on the pavement!!
So I called him a son of a mutant pig. He finished the second ticket and put it on the car with the first. Then he started writing a third ticket!!
This went on for about 20 minutes and the more I abused him, the more tickets he wrote. I didn't give a damn.
My car was parked around the corner...
