The priority list is a load of crap. I had a manager at AT&T tell me straight up that he had people fill out a form to be notified but if he has 10 customers at the store ready to purchase, he doesn't even bother with the stack of customers on the list. 
Edit: IT does make sense though. Why wait for someone to drive however many minutes when you can make a sell asap.
