Information Please?

I don't think I have a sign on my forehead that says "Get Your Life Altering Information Here". I really don't think so. So why is it that almost every time I go into a particular big box retailer(not the red one) I get tapped for information on products and locations? I never thought I had 'the look' of an information czar or anything. I even had one guy the other day ask me, when I was buying some shampoo for normal hair(you'll understand this point in a sec), where he could find on the shelf the best shampoo for thinning hair. I don't know why he asked me of the three people total in the aisle, but he chose me. I don't have a hair problem. My hair is not thinning, thank goodness. My hair isn't even as short as I want it to be. Maybe I shouldn't complain about that one. Last week a woman asked me where the extra absorbent pads were. I know I don't have one of those to reference!
