When my Dad returned to his job as a policeman after the war, he found that he was banned from playing for the police's rugby union team because he had before the war been on the books of St Helens rugby league team, and had played one or two games for them.

However during the war he had been allowed to play union for the army team. The police were obviously a bit snootier about it.

The class rules about gentlemen and professional players were applied with a good deal of vindictiveness.
