Hello sir,
I am a frequest travller in government buses.
I have been charged an exra amount of 30 rupees at night time, which costs 10 rupees at day time, saying bus fare is 40 for the same journey which is 10 at night.
Its not about money, but if we raise voice againest it, we were asked to pay 40 else we were asked to get out.
Many people paid the amount as it was the last bus.
Kindly look into it.
