Freecycle and similar websites

Living abroad as a kid in Taiwan, we had access to the American Px, the equivalent to our Naafi. One American woman wouldn't eat any eggs that didn't come from the Px. She wrongly assumed the Px eggs were imported alll the way from USA and that any local eggs were unsanitary and contaminated. When you think of where an egg comes from it beggars belief how she thought it sanitary or otherwise. I believe mum put her right.
