Do I really need to know the correct way to address a marquis or which fork to use for the fish? People who worry about using the wrong fork can fork off.
The matters that matter most in 2025 are more to do with mobile phone usage, as in, not talking to someone on it while a red-blooded, fully vocalising human is sitting right in front of you waiting for a real-life chinwag [that's called 'phubbing', by the way].
We clearly need an etiquette update...
