Doolie,
Your story exemplifies why I avoid music stores. I have some sympathy for the poor souls who must labor in these stores, but not enough to tolerate the stupidity of "sales kids" when it costs me time, which is my most precious commodity. There are just too many other good sources for these same products online and mail order. I can find out the information that I need on the internet or from a catalog, place my order, and never have to leave my desk. OTOH, when an emergency comes up, and I need something in a hurry on show day, I will send a "runner" to a local music store to go and get it, but only after talking to the store owner or someone else who knows me personally on the phone, and making sure they have it ready for pick-up when my "runner" gets there. It has taken me years to properly train the local music stores how to deal with a pro audio company. After a while, they finally caught on to the fact that I wasn't going to spend my money with them unless they can provide me with good service.
