Have you considered checking the timetable under "Sundays". You'll likely notice it's different from the weekday schedule.
Busses are not registered as a charity. They are there to make money. If the passenger numbers are there the opperators will run them. They are not going to lay on a bus and pay a driver and the fuel costs to run around and pick up a single passenger.
I find it insulting to wait so long for those lousy bigots only for them to be OOS. Makes me wonder why bother be on duty? o.O You're surely not getting paid with no service so.......*whistles*
its the SAS checking for terrorists
