Once I visited Hamad emergency at 10.30 PM with my friend who is severly shevering of fever. After about 45 min waiting time  met the Doctor and he advised to go to the health center as this is just fever.  Strange..  Night 10.30, a person staying in Doha should go to the health centre in industrial area as his card is registered there. His compnay is in indl area, so got registered  there.
