OMG, well it sounds like 8,500QR is not good. I mean as I wrote in the topic. Yes my salary is QR 8,500 straight to my pocket.
Expenses:

Grocery once a week, keep in mind I work all day so just one meal a day at home.
Nice dinner out once a week
Transport to work as I have no car, so that already is 1,000QR in taxis.
Once a week going out to a bar or club, but I dont drink that much.
Movies maybe 2-3 times a month.
I dont pay for phone, or house rent, or utilities, it has all been taken care of.

I dont really want to make a bad choice and take this job if the pay is not fair, taking in consideration that respectfully on that side of the world you work 6 days a week.
They mentioned that after 6 months they can review the salary and maybe up to 10,000.
