I have a limited vocabulary in headshops which consists of phrases like "that one" or "how much?" Because I avoid buying unfamiliar equipment (like unique bongs that seem complicated), it's always friendly and quick for me when I visit my local headshop. One time I had the clerk sell me some weed, of course it wasn't at his shop, we met him later. Good stuff, too, now that I recall. That along with the killer deal on pipes, bongs, hoses and hookahs, made for one unforgettable headshop endeavor.
