Am I dreaming that I have explained the origins of eating with ones fork/knife in particular hands TWICE now?
No, it wasn't for 'lazy waiters' either, and I am pretty sure waiting staff in large homes didn't get much opportunity to be lazy.
For the hard of reading..
Organising place settings all in the same direction looks neat, means you can organise who sits where the moment they enter the room, won't confuse guests.
If you have not seen a full formal place setting for 7 courses or 5 courses... I include a photo..
Trying to set that out, or even the slightly less complicated 5 course setting, some right handed and some left handed, would be a nightmare, would be very confusing.
Sitting at that setting and trying to swap cutlery over at each course would be disruptive and risk dropping stuff, clattering stuff, which disturbs conversation and draws attention.
And finally, sitting close together as one would be at a large but full, long table with place settings that big, in big bustly dresses or fluff sleeves - matching up left handed and right handed people the wrong way and you'll get elbows clashing and people feeling uncomfortable.
And there was a view that left handedness was just wrong and something to be corrected - and there were lots of shitty reasons for that and a few good ones (draw your sword with the left hand against a right handed opponent = die!)
I am not saying all this applies now, it doesn't, but this faux bafflement at the reasons behind these rules is ridiculous!
As for them being a weird British affectation... ha!
The Italians started this business with multiple forks in the 1500's, the French eventually caught on after several decades of dislike, and the British didn't go for the idea until 1633 as it was too effeminate! Up to that point, they were stabbing things with their knives and using their hands instead of a fork.
From there things went crazy and as the trend for banquets with piles of food laid out on the table passed, the one for huge amounts of cutlery and ceramic and eventually porcelain dining sets took off, as with food served by staff, there was now room on the table for billions of plates, forks knives, glasses, spoons etc. Mass production also meant that achieving matchy-matchy perfection became a thing.
Some of the rules don't matter so much now, we aren't eating at long tables, packed in like sardines with 9billion forks and knives to contend with. But I think those that involve not pinging food at one another or avoiding knocking stuff over are probably still worthwhile!
