What can I say..... Even if you show the *slightest* interest in a wee bit of merchandise, the proprietor will HOUND you to purchase it. NEVER settle for the posted price, it can be cut in half by the time you leave (if you can ever get out).
Unique Suggestions: Show ZIPPO interest in anything.
Fun Alternatives: Well, there's a Walgreens across the street.... (isn't there always?) Decent prices and somewhat hospitable. (Really wish I had a pic of this) :(
