Bangalore Metropolitan Transport Corporation [BMTC] — bus conductors not returning change but demanding change

Address:

500CA, 560037

I travel daily between kundalahalli gate and bellandur in 500-ca, and the fare is rd. 29/-.
The country conductors never return the re. 1/- change and i end up paying rs. 30 (Extra re. 1 every day = extra rs. 26 every month).
On the other hand, if we don't tender exact fare or don't have change of small denominations (Re.1/rs.2/rs.5), the same conductors shout at us in the bus like anything! If they themselves won't return our change, how will i pay them? Atms don't give re. 1/2/5).
Please ask them to return each 1 oe 2 rupees instead of personal gaining, or don't ask from us for the change.
