Not sure if you're being sarcastic. I never am, so it's hard for me to recognize in others...

The Big Orange Box guys are all over the lot, as far as knowledge goes. I've run into some very helpful guys around Philadelphia, and then there was the one in the plumbing section - I was looking for a specific type of faucet set for my wife's darkroom sink. I described it to the guy and he said sorry, no, they didn't carry anything like that. So I went off looking for other stuff, and eventually found myself back in the very same spot, only without the plumbing guy. There was the exact faucet set I was looking for. Not only didn't he know what the store carried, he had physically blocked my view of it!
