When I was six years old, I negotiated a raise for myself with the
captain of the showboat because I was making 50 cents and everybody
else was earning $2.50 a night and I didn't think that was right. So I
went to him on my own and I not only ended up with my raise but
everybody went up to $3.00. I guess that was my first negotiation.
