I'm a fast eater. A habit I developed at school.
The dining room couldn't accommodate everyone at one sitting, so there were three sittings in the space of 80 minutes or so. As a server I had to queue to collect the food in tureens, serve it out to a table of eight and then eat my own and then collect the dirty plates, return them to the counter and collect the pudding then repeat the process.
As a carrot to make the operation slick, the tables that finished quickly were often offered seconds.
