She and I both couldn't believe it, but a couple of men around the guy confirmed it, so she asked the security worker at the conveyor belt/machine if this was true and he said yes, this lane was for men and women had to go to a different queue. The reason I gather is that many of the pax going through security then were bound for Tehran, where of course this is more of a thing.
