I'm old enough to remember when Radio Shack was freaking people out by not selling them things if they had some unknown combination of components bought. They were so damn insistent on getting your address. Only store I always paid cash at because I was on an electronics kick and my friend had been told he was not allowed to buy some combination of components. That was friggin hilarious (he was building a controller for a pump), and I bought the components at another store location (Radio Shack was sadly the only game in town at the time).
