Breakfast is the most frequently screwed up thing anywhere, besides maybe hamburgers. My two favorites nowadays is the Full American (3 eggs, potatoes, bacon, toast) but 70% don't seem to get what I mean by "scrambled soft", the toast is often margarines (I specify buttered or dry) and the bacon is always crunchy- I don't know when that became a thing. Also peppers in potatoes as standard?
And the other is steak and eggs, but only Boscov's and a little cafe in Bristol PA (the Radcliffe) get what I mean when I say "Very, very rare, black and blue but skip the black!" By which I mean sear it lightly on one side, flip it, sear that side lightly, and put it on a plate.
Amtrak, oddly, was one of the few other places I could make that sort of request and have an odds on chance of getting it.
