Sounds like pretty common-sensical rules to me. Though why anyone would want to play during an air raid is open to question.
I've been reading a 1938 issue of The Aeroplane this past week, its odd how they used to write in those days and the humour is a little odd to understand, coming across as rather sarcastic at times.

Don't know many golfers, eh? They're pretty hard-core. The ones here in South Carolina brave alligators on the fairways without a second thought. They just play around.
