Address:

Gwalior

My Brother is in Army.
If i am right Rules are that tolls from active defense personnel are exempted.
But there is a toll in baretha Malanpur, in between Gwalior Bhind., they are charging tolls from defense Personnels and if going to ask why is it so, they start acting like goons!
Please Provide me A clarification is it right to chargecharge the toll or not!
