I'm gonna give you the benefit of the doubt and assmume that's a serious question.
From this thread it seems that not a few place a higher priority on having a sales person treat them nice than they do on price. That tells me that those guys consider good service more important than having to suffer poor service by rude or slow sales people than they do price. In other words they're willing to pay a higher price to avoid suffering the butt hurt of poor service.
Personally I don't give a crap how they treat me (up to a point) as long as I get what I want at a price I consider fair. I guess my threshold of feeling put out or put upon is lower than some. Each to his own. We all have different priorities.
I can't speak for anyone but myself but (refer to my post on page 1) but I think allowing someone to point a gun at another customer and not stopping them and then after it is brought to their attention and the clerk tells you to relax that the gun is unloaded. That goes beyond just bad service it is dangerous, negligent, and outright stupid. That is why they don't get my business it that means I'm butt hurt than so be it I can live with my bung hole sore.
