I was queuing at the ATM to withdraw some cash, but got stuck behind an old woman. She took about 20 minutes to get her card out of her handbag and into the small, card-shaped slot in the machine. Then she got her PIN wrong a couple of times before checking it on a small piece of paper.
At this point she started rummaging in her handbag for her glasses.
Eventually, even with the help of her glasses, she turned round and said, “Excuse me, young man, but could you just check my balance for me?”
It only took one shove to get her on the floor. Her balance was rubbish it turns out. I took the £500 though.
