Dilbert asks a salesclerk in a clothing store, "Can you help me?" The woman replies, "No, I'm afraid I can't." The clerk explains, "You see, I get paid the same low hourly wage whether you buy that shirt or not. And after years in this business I've learned to despise the general public." Dilbert waves some money at the woman and says, "Please . . . I have exact change." The clerk replies, "I have no way of knowing if that's true."
