mr. qatar-engineer seems more like the salesman at Strong rent a car.

Anyway, Qatar is one of the most expensive countries to live in. Agreed, this is not the case if your housing, schooling, etc are paid. But groceries are obv much more expensive than every country I have been to (except Japan).

Since qatar does not have income tax, assume you are taxed about 30% of your salary when you go to buy food, cars, groceries etc.
