Respect your elders.

Standing in a queue in Sainsburys, lulled on my feet into a semi-coma as it seemed like an age since I took even one step forward, when a young woman walked up to the next checkout and barged in front of an elderly man. Not a word from the checkout girl who saw it and despite disaproving call outs from her audience, she went through and paid for her shopping. I would have tipped my basket on her head and gone to Tesco's.
