Can't believe they not heard of orange chips in Bilston!! But as you say posh types so understandable lolAh, I see you answered my post here (I didn't read on).
A few years ago I was doing some work in Bilston and my colleagues (NHS types) had never heard of orange chips. So I took it upon myself to introduce them. Simultaneously horrified but addicted:
"These have to be sooooobad for you. But they're sooooo good".
I didn't get as far as the pickled egg. I think that would have been too much for them.
