"Hi, can I help you?"
"I don't think so. I'm just looking."
"Okay, that's fine. Are you looking for anything in particular?"
"No... well ... actually, okay, yes. I bought a scarf from you guys about a year ago, and I live in it. I thought I'd buy another one in a different colour. Wait ... I think I see them."
"Oh, yes, those are our most popular scarves. As soon as they come in, they're out the door. You're lucky."
"I guess so! But the truth is, I really don't need this scarf. I'm actually in a pretty foul mood. I just thought I'd come look, and buy one just to cheer myself up."
"Ah, yes, the Bad Mood Purchase. Sometimes, honey, you just have to shop that bitch out."
