A man in his sixties had approached me as I was about to visit the Fairprice supermarket today. He had wanted to know how he could pick up a call on his small Samsung mobile. I pointed out that the mobile was not ringing and he insisted that it was. After insisting a few more times, he decided to try a different tack. He pointed at his mobile and asked how he could check for missed calls. I observed that there was no indication that there was a missed call, there wasn't a missed call screen. I was suspicious. I had no desire to want to touch his mobile. I retreated with a smile and left him.
