Every time any character says the company name 'Fiscal Dynamics,' the line is over-dubbed from the original ("Financial Dynamics"). This was done, most likely, due to a real company by this name being identified between the completion of the script, and post-production.
After Jim first meets Arnold Love, he gets the check, which is dated '10 22, '74' - which, even though it's a fictitious prop-check, the date on it would be pretty accurate for when this scene had been filmed, as it's usually about 6 weeks - 2 months on average during regular season production for a TV episode to go from production to first airing.
One of the (very) rare times during the entire run of the series, in which a crowd is seen, being 'penned-off', as it were, so, as not to affect a scene. Not only that, but, right when Arnold Love opens the door, to Broadway Plaza, a businessman can be seen behind the 2 of them, who's obviously not an actor, but, just recognised 'James Garner'. When Jim and Arnold Love get to the bottom of the escalator, they walk to the (viewer's) right, and a rather large crowd can be seen (notably, a blonde woman in a red dress, with a cut-out top, at the forefront) standing next to the 'up' escalator.
