Now that you point it out, friends, it seems to me that the bartender, the farmers, Jimbo, L.D. and the calf ropers all look at Jack with a mixture of scorn and envy. The most sympathetic person, the other bartender, is only that way because Jack asks about Lureen, which is what a young man in a bar is supposed to do. He's following the script at that point, which is reinforced by the Texans.
