Hi-de-Hi! S03E05 - Trouble and Strife

Ted's ex-wife Hilary turns up. He is behind with her maintenance and could be arrested unless he gives her fifty pounds. Ted and other members of the entertainment staff manage to scrape together forty pounds through a series of scams but Jeff refuses to give Ted the last tenner as Ted still owes him ten pounds from the previous day. Eventualy Jeff relents but Ted is annoyed as he could have got away with giving Hilary forty pounds and has to admit that the bet he placed with Jeff's ten pounds made him a winner so he has to repay Jeff as well.
