Driving under the influence
At one point Van Heflin's character pretends to be drunk when he picks up a woman in the bar, and starts driving her toward Isabel's apartment. At one point she says, "Keep driving -- remember, you are in no condition to walk." My, how society's attitudes (as reflected by Hollywood) have changed in the past 60+ years toward the idea of allowing oneself to be driven in a car by someone who is obviously inebriated.
Life's a banquet, and most poor suckers are starving to death!
