I agree, saying hi and asking for names are totally different things. It's creepy for a girl to be stuck in the lift with such a guy.
But this kind of harassment is not unique just for Qatar, it happens all over the world.
I believe it is in much much less frequency in Doha.

So let's not scare all girls from taking the lift with guys. People judge the Saudis about their applications. But girls in this forum seem to ask for a separate lady's lift :)
I live in the first floor. Entering the lift, saying hi and getting out takes me 7 sec. no chance for a conversation even if we wanted to :)
