Sylvie Hicks calls on Mike whilst visiting her parents as her mother is ill with a heart problem. Eddie tells Annie about a pub which has started a happy hour. She refuses to consider the idea. Emily phones the solicitors and discovers that Arnold has died. Annie hears from Mike and Sylvie that all the best London bars have a happy hour but they call it a "cocktail hour". Pleased with this more "up-market" name, she feels it could help trade. Mike asks Elsie to help him win a business deal by making up a foursome for dinner with buyer Wilf Stockwell. She agrees. Emily feels guilty for not visiting Arnold in hospital when he wanted her. Annie announces a cocktail hour between 5.30pm and 6.30pm, during which time beer will be 10p cheaper and spirits half price. The enthusiastic male regulars get drunk as Fred and Bet are run off their feet.
