The actual cost or the meter cost from gorguntepalya metro station to my place in an auto is Rs 26 which I'm ready to pay till Rs 30 but every auto rickshaws near gorguntepalya metro station charge auto fair around Rs 50-60 saying they have to go alone back to station which I'm not responsible for over that they would scold me for asking to drop next to my place or would leave me a road behind my place which is not fair.
