Himachal Road Transport Corporation [HRTC] — Misbehave by the conductor

I boarded the HRTC bus no HP72B 6552 Shimla-Baddi-Una from Shimla to Kumarhatti on13:45 and took a ticket on 13:49:32 for Rs.128.I sat on seat no.4 but since it was uncomfortable hence I shifted to seat no.4. But, the conductor of the bus started shouting from behind that how I dare to sit on this seat. When I asked the reason he said that it is his wish to sit there but I reminded him that conductor has specified seat. On hearing this he started speaking in non-sense way and told me that I should not open my mouth. I simply told him to be codial with passengers so that our beloved HRTC flourishes but he said Iam nobody to teach him even if HRTC drown.
My only question is that shoul I board HRTC bus in future or not
Thanks 🙏
