Million dollar advertising campaigns paint this picture of a half dozen extremely knowledgeable staff of smiling faces who are ready to do whatever it takes to satisfy your every need. In reality, the job of "The Manager" (you so desperately seek out when you don't get your way) is to keep that place staffed to a bare minimum (they literally get bonuses for offering you less help). The staff is not paid nearly enough to warrant any kind of "knowledge-ability" but, in short, is there to get you from door to shelf. Excessive time spent helping customers is often punished because management's true focus is on stocking, housekeeping and satisfying the logistics of delivery and bulk quantity orders that keep their "big fish" clients spending the tens of thousands of dollars that make the sales numbers that keep them in their jobs. This is why when you say "I SPEND HUNDREDS OF DOLLARS HERE" everyone in the place stares at you like a complete ass-hat. That guy/girl climbing the ladder or stocking the shelves is the only person (and the lowest paid) who is actually there to help YOU out and 7/10 treat'em like shit.
