A parallel:
During my (mis)guided youth, there was no place in the world that I rather be than a nudie bar. Eventually, if a guy puts in enough time into these places, he gets a pretty good feel for the business. I came to to understand what appeared to be two different business models at work. In one model, a girl works the room, making the rounds endlessly, asking every customer for a drink or a dance. The fives and tens pile up and she makes a living. In the other model, a girl hates working the room and is only there to meet Daddy Warbucks. She will make the rounds with just enough enthusiasm to keep the management happy, but the last thing she wants is to be occupied with a small timer when someone she thinks she could cultivate into a cash cow walks in.
I think a similar dynamic takes place in high end audio, where a salesmen might be reluctant to be tied down to a guy who walked in with a cool grand burning a hole in his pocket and consequently miss the opportunity to sell a big baller.
