I agree for some of the jobs the conditions must suck but if I am not mistaken it is their choice to move and work in Doha. There are other places that they could go.

Despite what is happening in the working or personal life if they are in a service industry it should not matter. They are paid to do a job and good customer services should be included. As far as I am concerned when you are being served you should feel that at least for that moment you are the most important thing they are doing.

And before anyone asks - yes I have worked in services industries ranging from pulling pints, serving fish & chips to brokering commercial insurance polices. When I was working my customers came first, regardless what was happening in the background.
