I personally experienced that before,a man wearing a thobe and he showed an Id,and because we do not know about qatar charity,we just gave money...not only that...some arab women also are doing that..they pretend that thier love ones are sick...we knew that they are just lying,but still giving them even small amount of cash..but now...before i open our door...i have to check first if whos on knocking...hahahaha..if i see an arab woman again..i will never open the door...
