Bangalore Metro Rail Corporation — climbing on the elevators

Inspite of staffs warning not to climb on the escalators, people still climb and run through the escalator pushing by the other passengers standing on it.
Stairs are provided next to the escalator even then they do not use. I understand from a staff at vidhana soudha metro station that people shout at them asking them to keep quiet when staff insist them not to climb on escalators.
This is a very serious concern and to be restricted immediately.
I see this on daily basis.

Another nuisance is watching mobiles with loudspeakers on which troubles all passengers.
