Brice,
Yes and no or rather it depends. Most of the places like Rockler when they see someone lurking around a area they will at least ask if they can help you (me). They didn't.
Now other places I go to that are more for contractors I walk in look around and usually know what I want and if I need help Ill find someone. But that place is more like a warehouse with ply, timber hardware tools etc not a retail store.
But in the scenario I was describing its different then say the Woodcraft I go to. If they see me lurking around say the festool area, one will wander over and ask if I have any questions or if they can help. They know me by name.
I look at it as they want to make a sale.
