If the employee doesn't ask these things, chances are he wont be able to find a bike fitted to your body. You should give your target price range(don't know why I thought they said not to).
I've done this a few times, and it really separates the pearls from the swine. I'm totally biased, as I used to sell bikes for a few years. The "investigatory" approach is my style for anything I might sell to anyone. It's all about the needs assessment, baby...
WRT the OP, I always give an "Everybody okay?" when I ride by somebody stopped beside the trail. If they need help, I stop. The exception is if a bear is behind me on the trail. Then I just keep riding until I'm past them and then scream "BEAR". Bear takes the hindmost...
