Sherlock figures out man caught train because of food stain on clothes

[Alastair]

Hello Sherlock brains trust, I am hoping someone can direct me to a clip I saw years ago of a man meeting Sherlock at Baker Street. Sherlock figures out the man has caught a train to see get to London based (partially) on a food stain on the man's clothing. I have tried searching for this but no luck, I appreicate any reference to episode and season. Many thanks.

Hello, Alastair, and welcome to Sherlock Forum!  

That sounds very much like an early scene in "The Hounds of Baskerville," episode 2 of season 2 of the BBC program Sherlock.  Here's the first part of it:

SHERLOCK (quick fire): You came up from Devon on the first available train this morning. You had a disappointing breakfast and a cup of black coffee. The girl in the seat across the aisle fancied you. Although you were initially keen, you’ve now changed your mind. You are, however, extremely anxious to have your first cigarette of the day. Sit down, Mr Knight, and do please smoke. I’d be delighted.
(Henry stares at him, then glances across to John who averts his gaze and sighs. Hesitantly, Henry walks back to the armchair and sits down, fishing in his jacket pocket.)
HENRY: How on earth did you notice all that?!
JOHN: It’s not important ...
(But Sherlock’s already off.)
SHERLOCK (looking at two small round white pieces of paper stuck to Henry’s coat): Punched-out holes where your ticket’s been checked ...
JOHN: Not now, Sherlock.
SHERLOCK: Oh please. I’ve been cooped up in here for ages.
JOHN: You’re just showing off.
SHERLOCK: Of course. I am a show-off. That’s what we do.
(He turns his attention back to Henry and the napkin that he’s still holding.)
SHERLOCK: The train napkin that you used to mop up the spilled coffee: the strength of the stain shows that you didn’t take milk. There are traces of ketchup on it and round your lips and on your sleeve. Cooked breakfast – or the nearest thing those trains can manage. Probably a sandwich.
(Henry half-sobs, over-awed.)
HENRY: How did you know it was disappointing?
SHERLOCK: Is there any other type of breakfast on a train?

That quote is from the transcript by the amazing Ariane Devere.

The episode was based, of course, on Arthur Conan Doyle's novel The Hound of the Baskervilles, but a quick scan of the book's text turns up nothing like that scene, so either it was original with the TV show, or the writers borrowed it from some other ACD story.
