Bengaluru Metro Rail Corporation [bmrcl] — Failure to follow Covid protocol

I am a regular user of Namma Metro and the services provided are excellent !! However off late I see that security personnel and even frisking personnel do not wear their masks correctly especially at Doddakalasandra and Majestic stations. Their masks are most times below their chin or nose and this is not right. Request the concerned to take proper measures in educating them appropriately.
