BPCL pumps in Bangalore — Charging for free air

Address:

Bangalore, Karnataka

I want to know why most of the pumps ie BPCL-IOC-HP are charging Rs2/= or Rs4/= for filling air in 2/4 wheeler respectively in Bangalore.No where in Karnataka pumps are charging but in Bangalore city the pump people beg from the customer for FREE AIR SERVICE.If you do not pay them they abuse.
is it a guide lines from Oil company to beg for money for FREE AIR.
Even in other states like Maharashtra-Rajasthan i have seen that AIR is provided free..
But in Bangalore itself if you take AIR from Shell/Total air is FREE with dignity and respect.
Is it an understanding between oil company officials and the pump owners on this issue.
Its not a question of money but the way these beggers(Air service employee)behaves is shameful and some time they use such a filthy words no one can imagine.Also these people are not afraid of Oil company officials as well as they do not provide complaint register.
