recently when I was in line at the airport, I saw a big man. Very tall and in perfect health. He was wearing the traditional white clothing, but I couldn't really tell if he was qatari or not, as not all thobe wearing people are qataris. He had a maid with him. Definately not a wife. It was not just her clothing, but the expression on her face. She looked empty, without any hope. But that may just be speculation on my part.
The thing is, after asking the maid to give him their passports (she was carrying everything), he ordered her to lift up the luggage onto the conveyer belt. Anyone watching could see she had to struggle. Each bag was huge and certainly looked heavy. He just watched her. In the end the staff had to come to her help.
He didn't even bat an eye.
So, he's travelling with his slave, er sorry, his maid and I guess it's part of her job to help him?!

I know this sounds contradicting, but I don't mean to generalize. This was one isolated incident and I certainly haven't seen similar, but then again, seeing it once is enough.
