Mother Dairy — misbehaviour with customer with unprofessional attitude

Address:

New Delhi, Delhi, 110085

This is with regards to "mother dairy booth 567" located near sector 6 rohini, delhi.
The incident happened recently.
The lady in the booth often delays the process of selling milk to people either by indulging in unncessary talks with a few other people, or by intentionally feigning ignorance.
Recently she misbehaved with my relative when she was trying to call her for attention. As usual, my relative called her as auntyji out of respect.
She however took it the wrong way unnecssarily and started badmouthing the customer (My relative) by saying she was dumb not to notice that she was younger and so should not be called auntyji.
It was very rude and disrespectful of the booth owner to talk in such a manner to a customer.
Saying such unncessary things and arguing with customers for things which are not even legitimate should not even be allowed. She is often found indulging in such rude behaviour on a regular basis.
My request to the concerned authorities would be to take strict action against such people.
Kindly create an awareness that such behaiour is not acceptable and will not be tolereated.

Awaiting for a positive response.
Thanks and regards
