Is it me but has the P4 become very unreliable of late? Luckily I don't use it much but when I do, it doesn't seem unusual for there to be a 25-30 minute gap. More than once I have been on a bus where an announcement is made that the bus will terminate early, obviously to try to bring some order back to the schedule. Last Friday at about 22.45, coming from West Dulwich Station, I walked all the way from Dulwich College to Fairlawn School without one passing me. I know it was never a great service but I do feel it has deteriorated in the last few months.
