Hai..all
you just blame him( taxi driver),but you all( special for ladies)
Did you introspection with your self,your cloth,your body language etc?
If you wear Abaya( I mean covering body when you travel only,or wear whole the time is better)
Don't take any action, don't talk with him,just give him your destination khalas
Insya Allah you all will be safe
Qatar is peace country,we should keep with our attitude
