Finally, there is the mobile pest. I usually meet him at airports. He has an overloud, irritating voice. This is the kind of creature who will alight from his car, mobile sticking to his ear, check in without removing the gadget, walk to security in a similar pose, cross the air-bridge and take his seat on the aircraft still glued to his instrument. Eventually, he has to be told by the airhostess that the plane is about to take off. Passengers like him should be barred from travelling. My request to Prime Minister Narendra Modi, who seems determined to change the face of India, is that he should ban the use of mobiles at airports.
