don't be submisive make a big noise ask to see the security manager and also do some research into qatar law i am sure they put something in there about no discrimination. i hate family days to, the fact i can walk straight pass security guards because i'm white and the indians and nepali people i work with would get stopped. i once called a friend to meet me in the park at the corniche and he was refused entry until i went out and walked him passed the guard. good luck
