These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternative Character Interpretation: Jeffrey is being divorced by his wife, and is always turning down Gladys. Either he's simply at the end of a bad marriage, and understandably terrified of Gladys, or he's gay.
Fridge Brilliance: Maybe the reason Clive can't take anything seriously is due to all the horror he saw in World War II? You don't get to be a Squadron Leader by shuffling paper at a supply depot in Sidcup, so he would have seen a lot of horrific things.
The Woobie: Peggy. The audience adores her. Su Pollard gets more applause and cheers from the audience than the rest of the cast put together.
