Well I can say living in 2018 maybe a hand full of these may go but some of these are out of date and for the Bougie just have respect and treat people as you would like to be treated that is all. The rest with the servants is stuffy🤦🏽♀️ 1920 rules.
That is the point. Nearly all of my posts are of the manner of our grandparents who went to serve in WW1. The point of etiquette is, that it is never out of fashion, and if it sounds formal, may be transposed to a modern setting in a modern manner, and present politeness in the world.
Keep on keeping on. 😇
