RadioShack Idiots

I'm having a really big problem with the radioshack employees. They know little to nothing about electronics. I go in today to buy some connectors/adapters and the gentleman asks me if there is anything he can help me with. I respond with "where can i find TRS adapters?". To which he replies in his "know it all" demeanor "what are you talking about, I've never heard of TRS before. To which I responded "Stereo 1/4in or 1/8in adapters... TRS is the technical term. Radioshack was originally supposed to be a store where you can go in and buy parts to build a radio but the knowledge of their employees leaves me lacking faith that anybody knows what they are talking about anymore. The employee's pretentious attitude came off trying make me feel like i knew nothing about electronics when in fact i knew 50 times more than him. the nerve.
