Because nearly everywhere I go these days black pudding isn't automatically there (a huge number of places don't sell it as it is forbidden for a lot of their customers), hash browns don't usually appear and the toast is usually an extra if you aren't at a transport cafe.
(I miss the old place in Bradford - there was a transport cafe at the end of the road. Excelent food, and since the owners lived there anyone blocking the driveway was made to move before taking another mouthful.)
That's one hell of a Dagwood right there...
