Alf ran the snack bar at Knapford for many years until he retired in 2005. Upon his retirement, no suitable replacements could be found, hence the snack bar closed. Later on, Nelly was hired to run it. Alf's food was said to be so delicious that James had to blow his whistle to remind the passengers to catch their train. He used to joke that the passengers would rather miss their train than Alf's food!
