I've never seen nor heard of them anywhere in Scotland, but I have seen them in the Midlands.

I saw them on the menu at a chippy food cart at glasgow comicon this summer, so they exist here. I did not order one, but they were for sale. :)

I haven't been to Scotland in over thirty years, so I might as well toss my opinion in as "fact", as well.
