Bengaluru Metro Rail Corporation [bmrcl] — Inhumane behaviour by metro Staff

Today, my wife was travelling in metro at around 8 am in the morning, and after 2-3 station the mask which she was wearing came down and she is a medical staff. She was with no money during that time and the staff who came to collect fine, forgot humanity and behaved rudely and took 100 rupees which was left with her to leave her. Will you at any time justify this kind of a behaviour. The staff name is Mamatha B. [protected]@ybl is her upi id. I can understand people taking bribes, but making it digital can be done only by you BMRCL.
