On the Buses: The Other Woman

Olive is offended when Arthur gets too friendly with Wendy, a conductress he met at the social club, and she leaves in a huff with Mum. Arthur fails to come home and Olive, believing the worst, throws him out.

Mum tries to get Blakey to sack Wendy for immoral behaviour and Olive accuses Wendy of stealing her man to which Wendy points out that she has no interest in such a shrivelled-up old loser and it is revealed that Arthur in fact spent the night asleep in the sidecar as he couldn't kick start the combination. Appreciating that Arthur was faithful to her Olive has him back.
