I actually wouldn't want that power. Getting my hair chopped off is already the worst thing imaginable, but with Samson's hair, the worst thing imaginable becomes SO MUCH WORSE STILL.
I hear there's this thing called The Vagina Monologues....
That said, I don't know what its about, I don't know how popular it is / was, and I don't know how well it "speaks for" the "average" woman.
I'd PREFER to wash my hands with soap and water whenever I go to the bathroom, but I can't tell you how many times I've used the bathroom at work and every soap dispenser in that particular bathroom is empty.
I might be wrong, but I would think retail wouldn't be as bad, because people are actually interested in what you are selling. Why else are they there?
