National Highways Authority Of India [NHAI] — bad behavior on asking for delay

We are on national highway no. 15
Sanchor to badmer highway
The staff there was talking to a truck driver since 12-15 minutes. When he took his truck ahead we asked the staff member why it did took a long time to transact then the staff members replied us with a very rude tone and started to use abusive word.
Children were there with us and no one expects this type of service. So i kindly request you to take a quick action as soon as possible and help not only us but each and every traveller from avoiding this unnecessary abuse and delay
