More checkout chat

I was just in M&S food dept and saw marvellous customer service. The lady in front of me was obviously very elderly and looked rather fragile. I'd noticed her on my way round the shop.
Anyway, the staff member on the checkout very carefully packed all her shopping after it had been clicked through and was endlessly patient as the lady struggled with her purse and card. All the time she was talking kindly and pleasantly and got out from her seat to help the lady put her bags in the trolley and helped her on the way out of the shop.
I was so impressed at the kind way she did this. No fuss just great to see.
The self checkouts were empty.
