Happy is the man who can make a living by his hobby! You can spot an Irishman or a Yorkshireman by his brogue. I can place any man within six miles. I can place him within two miles in London. Sometimes within two streets.

“Poor girl! Hard enough for her to live without being worrited and chivied.
THE GENTLEMAN [returning to his former place on the note taker's left] How do you do it, if I may ask?
THE NOTE TAKER. Simply phonetics. The science of speech. That's my profession; also my hobby. Happy is the man who can make a living by his hobby! You can spot an Irishman or a Yorkshireman by his brogue. I can place any man within six miles. I can place him within two miles in London. Sometimes within two streets. THE FLOWER GIRL. Ought to be ashamed of himself, unmanly coward!
THE GENTLEMAN. But is there a living in that?
THE NOTE TAKER. Oh yes. Quite a fat one. This is an age of upstarts. Men begin in Kentish Town with 80 pounds a year, and end in Park Lane with a hundred thousand.” source
