I have been doing a lot of reading on the culture, and I think avoidance is your best bet if they are kids. Qatari or non-Qatari, kids seem to be put on a pedestal and highly valued, and, shall we say, indulged? My understanding is that one will never see a gulf child be spanked or physically punished. I sure wouldn't want to be seen kicking a boy where things count! I wouldn't do any kind of physical retaliation unless it escalated beyond harassment into real danger.
