Of course, that can very easily backfire. A *LOT* of people'd give nosy buggers like that the stinkeye and then never come back. If the customer looks like they actually need help, fine, approach with a "Can I help you?" or equivalent (and, seriously, give them at least a full minute - they might just be a browser rather than need help finding something!), but otherwise leave them alone and wait to let them come to you for "engagement".
