I suppose it could be Damon Runyon - he rarely used contractions in his stories - but he had a florid, tough-guy style that was usually applied to gangsters and detectives and suchlike, to show that they were tough buys. In fact, if I remember correctly, that post was in reference to a somewhat hard-boiled story, so it made a bit of sense there, even if it didn't work very well - it does not work here.
