There were a couple or three occasions in my misspent youth when I found myself unable to return home for the night, and therefore ended up sharing breakfast with my impromptu hosts. One time it was canned tuna and spring onion with mayonnaise on toast and a lot of instant coffee, and the other times there were full fry-ups, English-style, with egg, bacon, grilled tomato, the lot. Also hot tea with very much milk in it. Damned if it didn't do the trick! A quick shower and another thousand-or-so cups of tea, and we were ready to hit the tiles all over again.
