Goodbye, Paul? is the 21st episode in the series.

Plot synopsis

Paul announces that he is selling the hair-dressers to open a beauty salon but cannot find a suitable venue. Howard suggests that elderly ironmonger Mr Lazenby may want to sell his shop but Paul finds him unreceptive. Then Martin goes shopping at Mr Lazenby's and, concerned that the old man is suffering from dizzy spells, advises him to sell to Paul. He thus becomes a reluctant hero though it does lead to a heart to heart with Paul which, of course, achieves very little.
