National Highways Authority Of India [NHAI] — Misbehaving of toll gate staff and use of profanity.

Address:

Dahalapara Toll Plaza, National Highway 31, Moutara, Assam 783390

While I was traveling from Bongaigaon to Guwahati, i came accross the toll plaza at Dhalapara, Bikni which had some issues for which we had to wait for more than 5 minutes. And when I asked how much time I need to wait, they started yelling ate and using profanity.
If this is how toll gates operate then it will be difficult for us to travel.
We pay so that the service we receive is of high quality but this is absolutely not acceptable.
