"Miss, how much money do you spend on your hair every month?" he asked me.
I stopped and thought about it. "Why?"
"Well, I'm doing a salon promotion, and I bet you we can save you at least $10 per month on hair cuts and more."
"The last time I got my hair cut was in April," I told him. "Of 2006. And it cost me $5."
I watched his reaction for a second, just because his speechlessness was so amusing. And then I got on my train.
