Totally unimportant things that drive you insane.

People who say contra bute instead of con trib ute

sellotape

People who chew noisily, or with their mouths hanging open, American ads (they are fine in America but here on U.K. tv I find them jarring), people who walk slowly in the middle of the path, Gosh a lot of things annoy me

The chemist who delivered DH’s medicines, but not mine. To be fair DH doesn’t know why that happened.

I am unapologetically annoyed by Americanisms - REEsearch being one, ‘normalcy’ another, and ‘stay home’ makes me cringe every time I hear or read it. Stay AT home is the English idiom.

People who say or write 'normalcy' instead of 'normality'. Grr.

And move on to advertise and advertisement?

Sorry I just carried out research rather than read about it in dictionaries.
Discuss export and export as a noun and a verb.

Aveline, I just checked in my very big fat Oxford dictionary. which tells me that REsearch - whether noun or verb - is the American pronunciation, which is (unfortunately IMO ) becoming more common in the UK and is now generally accepted.

Yes, Jacky you’re right. I’d love to win it tho, whatever they call it! I love that show.

Why do they refer to the suitcase prize on House of Games as "Luggage"?

Surely it's not luggage until it's got something in it?

Yeah, no. I agree.

readsalot- people that criticise other people's grammar.

Aveline

People that criticise other people's speech!

People WHO criticise other people's speech.

Canadian Gran That photo sets my teeth on edge, i could not settle if my switches were like that.

CanadianGran sorry, I deliberately have our row of three switches hall, porch, stairs up/down/up. I’ve even been known to make an extra trip upstairs to put that right!?
Aveline you saved me a post. Thanks.
Sodapop the hotel showers are often a nightmare. I used to send DH in first to get it right.
My pet hates:
Being the person who doesn’t get the solid chocolate fingers in a Kit Kat, especially when I had first choice of biscuit.
Also people who carry on reiterating that they, and only they, are right, even when you’ve given up the discussion.

It's a source of annoyance for me that not only are a lot of the light switches upside down, they are in the wrong place, compounded by the doors opening the wrong way round!

Canadiangran- I agree that I prefer both switches to be either up or down but for me it's down for on and up for off!

Canadian Gran I've just asked my husband "what is wrong?" on your photo.
Straightaway he said what you've complained about ?

Checkout staff that pick my very fragile and expensive Gluten free loaf up by the middle AAGGHHH use the ruddy long piece of wrapper at the end !

Witzend- re research/researching - pronunciation depends on whether that word is being used as a noun or a verb.
Ie my reesearch is into X or Y
But I'm re search ing X or Y.
I know I'm being pedantic but I only discovered this relatively recently!

My daughter and me found that people hereabouts (including us!) say "yeah, no" all the time.
No idea why.

People who begin answers with, ‘Yes, no....” (which is it???); the frequently use of ‘ visceral’, ‘nuanced’ and ‘heads up’; the BBC using two subjects and a singular verb.

People saying REEsearch instead of reSEARCH.

Buying something new, usually electrical, and finding the instructions are printed in fourteen different languages in very small print.
