Karnataka State Road Transport Corporation [Ksrtc] — Rude behaviour and returning the change

On 21/03/2023, I boarded KA 19. F. 3433 (Kasaragod to Mangalore KSRTC )bus at approximately 9:30 AM.
The conductor was very unprofessional but also disrespectful towards women. I
Provided him the ticket amount and he refused to return the change even though he had the change in his hand . He was planning on keeping that change for himself. He told me I won’t return your change and you had to bring the change from your home . I agree if he didn’t have the change amount but he had lots of coins in hand and he gave change to people who look elder . Since I look very young and small he thought of keeping the change for himself thinking I won’t dare to talk to him . Also he behaved very rudely.
This incident has left a negative impression on KSRTC. And I find Kerala ksrtc conductors behave in decent manner. Why do you still keep conductors who are disrespectful to women and try to loot the money of poor passengers.
I kindly request a thorough investigation into this matter and appropriate action taken to ensure such incidents do not occur in future.
