Chance often determines how a young person finds her calling. In 1949, I was majoring in Biology and Physics at Bryn Mawr College. I took a summer job (as usual) to earn money, this time waitressing at a resort hotel in the Pocono Mountains. We were given uniforms, including hairnets, and were told to prepare for training. The training turned out to be daily practice in serving the older, permanent waitresses, who did not tip and did not like Jews. After a few weeks, I was finally allowed to work in the main dining room.
