I've seen many videos about migrant workers in Middle East, and I highly doubt that they have money to spend in malls or have proper living conditions. E.g. https://www.youtube.com/watch?v=I0EsOFDA6uM#t=3m24s (though this video is from Qatar, there are similar from Dubai)

You have "seen videos", but have you ever actually been to Dubai or Sharjah? The lowest tier of workers toiling in squalid living conditions is not the entirety of Indian-subcontinent workers in the UAE. For decades the Emirates have had a huge population of Indian-subcontinent (and Filipino, and Eastern European) migrant workers who work all the service-economy jobs so that the local Emiratis don't have to, and yes, these workers like the malls, too. Even if they don’t have so much money to spend in malls, malls are still the place that anyone goes to have a stroll around on a day off, because as air-conditioned spaces they serve as the local parks and squares.
