Tony Payne, chief executive of the Federation of Licensed Victuallers Association, said: "I would be very surprised indeed if even one pub stayed open for the full 36 hours, and the reasons why are obvious. First, a pub staying open that long would need a big clean-up, and it would be extremely difficult to stop everyone while you did it, or to clean round them. Then there are staffing issues, and the fact that it is illegal to serve a drunk person - which might be rather difficult to abide by if the pub's open for 36 hours.
