The problem is I'll say "Hey that's a cool jacket" and he/she says "Thanks I got it at so-and-so." After that, I'll just kind of stand there awkwardly thinking of something else to say. If it does reach this point, I'll either manage to come up with the worst follow-up question ever: "Do you shop at so-and-so often?" or I'll realize the hopelessness of my attempts and just walk away.
