National Highways Authority Of India [NHAI] — Abusive language used by toll plaza employee

This is about an employee's misbehavior who used abusive language today on 16th August 2021 morning. I asked about the time limit for waiting in the queue at the toll plaza on which the employee used abusive language. I have no recording or any proof as such and I was in hurry so I ignored the matter.
It the first toll plaza on NH30 at Ronahi between Ayodhya and Lucknow highway.
This is not the first time when these guys have behaved this way.
