I feel sorry for the people that have to work there. Most probally are getting paid 7 bucks an hour to deal with over zealous critical people like yourself. I have had nothing but good experiences at my local Apple store. Whenever I have a problem, they go above and beyond what other like retailers would do for their customers. To me it sounds that you just have nothing better to do then to nit pick and go out of your way to trip the sales people up. Just like a big bully. Grow up. There are better things to do in life.
