I think it is easier to just step back. They are totally different, many times irrational and emotional and extremely self absorbed. The LBS is the last person they will listen to in most cases anyway and there is a level of discomfort there. You have no idea what they will say or do next.
I like to look at them like a unpredictable tornado. If you were to see one coming are you going to try to reason with it? Pretty pointless. Just get out of their way, and let them whirl.
