This time of the year is very busy and it's easy to be impatient, particularly when grocery shopping. The L sign in front of this young cashier at Harris Farm Markets Randwick is a clever way to encourage patience. If you choose her queue, as I did, your expectations are lower. It was a pleasant surprise when she exceeded expectations. I told her the sign reminded me of a joke my son made that I should put an L plate on my car so drivers behind me would not become impatient with my slow driving!
