Smoke Without Fire - S2.E5

Dudley decides to give up smoking, and begins to suffer withdrawl symptoms after two minutes. The girls' pregnant friend Ann and her door-to-door salesman husband Freddy pay a call; the latter has taken Susan on as an apprentice, and they are set to descend on the Hampstead Garden suburbs with their product - The Little Wonder Household Implement. The lease on Ann and Freddy's flat is up and they can't move into their new house until Monday, so Ann prepares to waddle down to a hotel to book a room for the weekend. Jacqui suggests they stay at the flat instead, she and Susan sharing one bed whilst their friends sleep in the other. Dudley jumps to the wrong conclusion and assumes a boyfriend of Susan's has stayed the night.
