Think there's some misunderstanding here. If you read the original post back, the author was simply making the point that the diner was the same location used, and that it was nice to see it in that context. I don't think there was a suggestion that it was filmed at the same time or anything like that, simply that the location was the same and that nice 'coincidence' that it is used in different Channel 4 Television idents.
Thanks. Yes it was merely that I noticed the same location used by both channels for their idents. Never thought they were made by the same company or at the same time. Just noticed that I said ident instead of location, my bad.
