According to a new survey, the disappearing habits include not talking with your mouth full, not eating until others have their food, using your cutlery and not your fingers, family mealtimes, saying thank you for your meal, and asking to leave the table.
Mealtime etiquette isn't entirely vanishing though. The old rules are being replaced by new ones, such as no vaping, putting mobile phones away and not having loud phone conversations at the table.
I've had heated discussions with people who still stick to the traditional rules and object strongly to anyone ignoring them.
But as I've said before, surely the point of a meal is to enjoy yourself and have an interesting conversation. It's hard to enjoy yourself if you're constantly wondering if you're breaking some unwritten rule of etiquette and afraid someone will object to your uncivilised behaviour.
Mind you, there are some habits that really ought to be frowned on but never are. Like getting hopelessly drunk and annoying everyone in the vicinity. Like letting your children run riot and doing nothing to stop them.
Not to mention those hardened drinkers who urge their neighbours to "have a top up", even if they don't want one. With the implication of course that if they aren't happily refilling their glasses they're some kind of party pooper.
I could think of worse things than being a party pooper.
