Himachal Road Transport Corporation [HRTC] — monopoly during dinner while coming back from manali

I am a traveller of bus no. Hp 63 5854, manali - delhi, dated: 1 st april 2018 (3pm bus from manali).
The bus was stopped at plaza food corner near bilaspur by the bus driver at around 9:50 pm.
The food plaza runs monopoly and offers only buffet of 180 inr/head... No ala carte available. On being asked to the driver and the conductor to stop else, was simply refused saying it's late.
The hotel owner taunted saying "you're bengalis isliye apka zyada dimaag chal raha hai.. Baki logo ki tarah chupchap nahi kha sakte".
My point is why such monopoly? And why such mis behaviour?
Now my family will have to go empty stomach.. There are no restaurants around. Only tuck shops.
Can anyone help?
