I went in to get some guitar strings and a short 1/4 cable one day. The sales guys in the guitar department were extremely condescending, told me that I use the wrong strings for my guitar (and I've been playing shows on them, thank you very much) and wouldn't sell them to me. And then they said shorties only come in a pack of six...as if I haven't bought single ones elsewhere before. The bowed string section is also quite snobby.
I think for guitar type of stuff, your money will be much better spent at Long and McQuade; and bowed string stuff go to the Soundpost. You'll have much better selections, and more importantly, you won't feel like crap walking out of the store. Will probably never go there again.
