You don't have to follow them, but you do you should be ready to accept the consequences of your choice.
In the area I grew up in, caring too much about useless aesthetic stuff like “elbows on the table” would have a social cost.
We just grow up with it because it’s how our parents and the parents of our friends speak.
If you want to change your accent you can, of course, get elocution lessons but most Brits do not. We just have a large variety of accents of which RP is one.
I didn’t have lessons for it and I don’t know anyone else that did. It’s just how we speak.
How so?
Interestingly, the sociolinguistic literature shows that such a consensus is strongest among an aspirationally upward-mobile social group rather than the already social elite. In other words: The aspirational middle class make a big effort to speak how they think the upper class speak in hopes of joining them one day.
Most people have settled into Estuary, which has split into a high/corporate/media Estuary-tinged dialect, and low street Estuary. The BBC has its own special neutral version.
Fifty years ago the difference between upper class/BBC/RP and street English was almost hilariously obvious. Watch a BBC show from the 50s and 60s - even something like Dr Who - and everyone is speaking a unique RP dialect that doesn't exist any more.
In media, you’re quite correct - it has become rare bar presenters who are now in their 80s or older.
Mind you, I'm not saying that standards must be followed. I am just saying the same thing I tell my kids:
- the standards are there, wishing they didn't exist doesn't invalidate them
- the reason rules and standards came to existence might or might not be applicable to our current context, but some people will expect you to follow them regardless.
- If a rule or standard seems silly to you, make your best attempt at understanding why people would still follow it. (Chesterton's fence)
- You are free to not comply to some rules, but always be ready to accept the consequences of your decisions.
- What your friends are doing or not doing is not reason enough for you to change your behavior or choices.
I had a friend who came from a working class culture where social aspiration was measured by tiny nuances, like whether someone put milk in their tea before or after pouring it.
Outside of that culture these nuances were irrelevant. Middle and upper class people had a completely different set of etiquette markers - as well as more or less obvious displays of wealth - which the working class aspirers were oblivious to.
If people act like a standard doesn't exist, then the standard actually doesn't exist, because that's the only thing that defines a standard.
Standards are not absolutes.
But not observing them does. There are standards no one in the world follows anymore. They may still “be there”, but are only used for mocking purposes.
> If a rule or standard seems silly to you, make your best attempt at understanding why people would still follow it. (Chesterton's fence)
The corollary to that is that anyone who rebukes anyone else for not following a standard must be able to explain why it exists. “Because it’s rude” it’s not good enough, explain why it’s considered rude.
Are you just looking for an argument here?
Not quite. My original comment was in response to "I see people violating rule X anywhere, even though I was told it was 'wrong'".
All I am saying is one shouldn't be basing their behavior solely on what they see others "getting away with".
At one point in time, it was considered bad etiquette to interact with people of color, but over time, society changed for the better. That etiquette literally doesn't exist anymore. That doesn't mean people are "getting away with" not following a "rule" these days. But rather customs/morals/etiquette are transitory and prone to changes, and one must understand what is and what isn't actual etiquette instead of just following all outdated "rules".
That's also fundamentally different from something like a law, where the ethical thing to do is that you should still follow it even if others are "getting away" with it.
