Just had a cracker. Lad woke up just as I was about to take a photo (would have been a belter of a photo too) and shouted 'woooah!' at the top of his voice.

He asked a lass where he was at and then queried if this was past the stop he needed to be off at.

He pressed the bell immediately and walked to the front of the bus, asking if he could stop on the bus until it came back round - about a 60/75 min trip. 
The driver pointed out that the stop across the road would be the best bet and much quicker.

Gutted I didn't get the photo.
