Outside the restaurant

I'll mention a moment in the film that nobody else has brought up but that I found very unusual and perceptive. When the three sailors first arrive in Washington (I think) and are lookng for a restaurant (one of them has mentioned getting a hamburger), they look in the window of a restaurant they're passing on the street. What they see inside ( we get a good look) is clearly an upper class establishment with table cloths and with men in business suits and well dressed women. When we see the sailors' reaction they are clearly intimidated at the idea of going inside--even Badass looks a little scared--so they go on down the street and we next see them eating their burgers in a greasy spoon type place. Don't know why that moment stuck out to me. But very typical of the texture you'd expect from Ashby and Towne to acknowledge class distinctions (the type of thing modern Hollywood movies never dare approach).
