I have been trying hard to buy this film and others by Mike Leigh for a long time and at last managed to track them down in the USA.
This was an amusing film about 3 post office workers and their families. Stan who's wife had gone and left him was busy having affairs or chatting up his mate's wives and other ladies. His poor daughter must have found it hard when she came to visit from a children's home and it all came to a head in front of her. She may think twice about visiting her Dad again let alone living with him! I had to feel sorry for Harold, whatever he tried to do for for his wife (June) he couldn't please her and his attempts at humor failed to amuse his work mates. I think Hazel was simply being friendly when she asked Stan in for a chat and had no intention of having an affair with him. She is a friendly and outgoing. After all it was her husbands idea!
I found this an easy going and enjoyable film. It is light hearted even the social worker scenes. The social worker at the end is either eccentric or maybe highly intelligent or maybe a bit of both.
