From the "Bonnie's Niece" section of the site:
Bonnie Ray relates a funny story about the later years
Blanche and Billie Jean were little old grey haired ladies at the time and went into a Green Stamp place. While waiting in line at the check-out counter, another old lady needed to leave the line for a bit and left her big old purse sitting there, wide open and asked them to please hold her place in line until she returned. One, either Blanche or Jean, looked to the other and said "boy...if she only knew who we were"! Bonnie Ray said that she laughed at that a hundred times - thinking about these two little old ladies, "notorious women".
