Very interesting.
Alex's clientele were more of a social crowd who used it as a meeting place. He had the best pies by far. The Mobile was a 24ft long purpose-built trailer and was towed from Hollywood by Land Rover to its site on the redundant tram terminus lane directly outside the main entrance to the station, arriving at 6.30pm. The hatch would go up at 7pm and I used to close at 4am just after the 4am buses left.
