Is it just Sir Alan that uses this term or is it a 'London term' in general?

It always makes me chuckle for some reason!

Don't think it's particularly a Lord Sugar or a London term, it just means "provided".

I'm sick of that expression. I wouldn't mind, but he uses it so frequently.

Its quite a common, if maybe a little old fashioned, expression.
EG "I missed Mavis and Fred's party - apparently they laid on a good spread"

Mavis got 'laid on' the table.

Bligmy! Sounds like I missed a real humdinger of a party!

Apparently, she had a good spread

I agree. It's a pretty normal expression to me - but then I am a Londoner

'I've laid on a couple of coaches' conjured images of a very niche calendar shoot.

"The producers decided it would be great to....."

Normal English language expression to me.

I find it an odd expression. Until recently he was the only person I'd heard saying it.

It's a completely normal expression in my area as well. It just means he has provided something. Thinking about it, it is often used in relation to the meal after weddings or funerals. Or if the family are laying on transport to the reception or cemetery. I'm surprised that anyone finds it unusual.

I don't think I find it unusual enough that I'd question it if someone used it in casual conversation. It's just that Lord Sugar uses that expression so frequently that I have come to associate it with him.

i've always thought it basically means i have provided something at my expense/hassle, obviously with LS uses the royal "I" meaning he's decided on two coaches with the relevant logo's and the producers and their team will scurry around to make it actually happen

I just like to think he's actually laid on top of someone and he won't get off them until they agree to assist the Apprentice teams in the relevant tasks.

There's so much that is said week after week, series after series.

His script is the same all the time.
