I have seen invigilators checking boys. They will ask you empty your pockets and also lift your shirt so as to make sure there are no 'bits' tucked into the pants. Most likely the concerned girls would have also asked to do the same.
"True, but if they are taken out of the hall and searched they will loose time and there is no provision to compensate it"
WHAT? you would do that two ladies just to save 2 fking minutes? whats wrong with people man, this world is screwed up, instead of defending those invigilators you people should support the two innocent ladies, even we will support them along with you.
