I have discovered a benefit of being old and white – coming into Australia from Hong Kong all the ethnic Chinese were summarily ushered into the Customs Area to have their bags searched. Being old and white, we were asked if we had any fruit or snacks (I was tempted to ask for an orange and a pre-veggie Mars bar but thought that as I didn't look particularly emaciated he was just being hospitable). We were waved through the Green channel 'without let or hinderence'.
