So many bizarre facets to Pretzie's character. Once he latches on to Herc he instantly abandons his pretzel enterprise leaving his basket in the cab and never returning to his namesake job. That's completely understandable since he can't afford a $2 cab ride, let alone cover the $50 bet he makes on Herc's long jump competition. That certainly paid off though because he manages to use that to buy both himself and Herc new suits when they arrive in the very next scene for tea with the professor and his daughter. No wonder he's depressed at the end, he has no job, no one to leech off of and is probably still wanted by the mob.
Herc's understanding of technology and modern life is wildly inconsistent. They try to depict him as a fish out of water calling cars chariots and seemingly not understanding what a movie is on his date with the professor's daughter, yet seconds later he not only owns a camera, but wants to take tourist snapshots of her in front of statues of his mythological friends -- Atlas in Rockefeller Plaza.
