How knowledgable is the Gaming guy/girl at the store near you?

[lolita]

I go to EBgames sometimes and they're quite knowledgeable... They rip-off though. I buy sometimes used games there but never used consoles. I go to Wal-Mart too (hey a dollar less is a dollar less!) and there's this cool old lady who plays VGs. She has all the consoles and stuff! XD
