Given you pay for education in Qatar I would think if the parent had preferences and asked not to be sepearated from the child or in the same room they would not disagree, since the well being of the child should be in the best interests of the parents and the school! I do remember a very popular school in the past trying everything to only accommodate children from one company and they would use any excuse in the book to get rid of others. Who knows maybe the seats are extra valuable again these days. Given their are not enough spaces they can basically do anything, much like rentals, and food!
Supply and demand so to speak.
