this is also my long last question in my mind, and i made a long time research of this phenomenon...did you know that 90% of the hotel or building or any high rise building with more than 13th floor in the whole world has no 13flr? they always skip to 14th. because they believe that it will give you bad luck if you stay on the 13th floor...but here in doha i don't think they believe on this....
