Perhaps because they were listed as pies? ;) I grew up in Dorset with steak pies available, but it'd be an unusual order for sure, they definitely wouldn't sell many, you'd probably waiting a few minutes for them to.. microwave it I suppose.

I can't really think of anything we had that's region specific, mostly just fish and chips, with fish cakes, sausages, pea fritters, and occasionally pies also available.

Definitely no gravy, except at Chinese takeaways, (along with 'curry sauce' and sweet & sour) on greasy fries of course, not chippy chips.
