Think about it, there could be another reason, incorrectly written running board!

That's reminded me of one of Stagecoach Nuneaton's old running boards actually, according to what it said, you had to go back in time 5 minutes to get to the next timing point!
Plus, at the time, every single one had the wrong inbound bus station stand on it! I.e. you could do 7x route 5 in a row, leaving from stand A3, but it would tell you to drop passengers off on a completely different stand when you return, then be expected to pick up again on A3 for the next trip, which would mean exiting the bus station and re-entering again!
