Once I was in the parking lot of a shopping center, when I was approached by a pretty young woman who had worked as a waitress in a restaurant that I used to go to. Nothing unusual about that. Any time I was in the restaurant she simply took my order. But now, she told me she had lost her job and, stuck for money, said she would supply “whatever I wanted.” She gave me a card with her phone number and with a gesture that left me in no doubt what she meant.
