Colleague's speech patterns annoying me

[cardboardPeony]

I think I probably ABU but I have a colleague who uses phrases like "X is going toilet". This really grates on me but I don't know how to say that it does or if I'm just being unreasonable and it's a regional thing.

Also we work with children and therefore should be using the language we want them to use, especially as lots of them are just learning English, but I think I am going to sound like a major pedant bringing it up.

Kitten - I really want to know what town it was.

Kitten- town will be either St Helens? Prescot? That way somewhere I would guess...

SE London here. I hear it all the time. Does my head in. Particularly 'going Nando's'.

A variant I hear Irish people use is 'going asleep' rather than 'going to sleep'. It sounds odd to me, but isn't as annoying for some reason.

The two things that really do my head in are people who end every sentence 'Do you know what I mean?' And people who use fuck/fucking in every fucking sentence.

Zoflorabore you're good! It was Widnes actually. (Right next door to St. Helens and Prescot, for the uninitiated.)

If I got pulled up for how I speak it would only make me do it more. I have done in the past. I just get more "common" the more someone complains about it! I am really petty though

Leigh folk have a great accent.

I notice somebody has a syndrome which makes this offensive....ah well

Slightly off topic but has anyone noticed the Real Housewives of Orange County say they are " going potty" ?
That sounds really odd to my ears.

randomer Is a leighther yeh!
have you heard Andy Burnham recently, he's gone a bit southern and posh

YANBU OP. It is a grammatical error, she needs to set a better example to the children with ESL.

Andy Burnham is brilliant.

My favourite go-to accent is the late great Ray French. It's the voice of wet chilly weekends and sweaty clubhouses.

This isn't an example of a speech pattern, it's a colloquialism.
I'm snobby about 'toilet'.

East Midlands here too. I say "going toilet" and "twenty pound".

Please don't hate me

My lovely bright niece says 'so fun' instead of it was such fun!
