He solves the problem by pretending that he's blown all of his money on expensive watches and Harrods lager.

Dorothy and Deborah have gone away on a sailing weekend. Tony is building a sauna in the garden shed - a ""shedna"" as he calls it. Gary and Tony meet Paula and Carol, who are staying at the house next door for the weekend. They invite the girls round for a barbecue. Tony makes a play for Paula, but discovers that she's a happily married mother. Gary is seduced by Carol.
