rlasrado, please explain this logic to me.
First you say that a person would not accept a salary in Qatar lower that what he is paid in his homecountry ( now we all surely realize that his salary at home is , besides other factors, based on cost of living,right? )

Then you say that if a candidate during an interview with you mentions cost of living at home in connection with a salary here is hilarious.

Now, some might mention this, others won't. Both have their reasons. One would be that mentioning the obvious is uneccassary for some.

Still, can you enlighten me? (I would be one of those not mentioning the obvious)

What comes around, goes around....
