South Asians are the working class in Saudi Arabia--mostly Bangladeshis, but plenty of Pakistanis, Indians, and Sri Lankans. They are paid poorly and live in miserably-crowded conditions often hours away from their place of work, bussed in and out daily. Most of the money they earn gets sent back to their families, so they have little in terms of spending money. I visited this particular shawarma shop daily (sometimes twice a day) for about a week. By the end of it, the workers were used to my camera.
