This boring dude Qailash Kher sang boring songs and people completely disliked them and every time he stopped, they kept yelling AATIF AATIF and he completely ignored them and kept going on.
I just got back from the same concert (the Toronto leg of the tour).
This time Qailash snapped when people yelled Aatif Aatif and started giving a lecture about good manners and patience.
