Money spent for no value in Nandini restaurant

We have been to Nandini restaurant MG road Bangalore and ordered 3 meals for 3 persons, each cost Rs.140
As I was not hungry, I asked for one small bowl plain rice. When the bill came, I was shocked to see that for one small bowl of extra rice alone it costs Rs 110 where as a meal Rs 140. Are they making fool of customers . I could digest if it was 50 or 60 Rs though it's the cost of one kg rice.

I am not sure if others also have this feeling or only I am thinking so.
