We have so many dispensable GROs so it is not hard to recruit them. Assimilate recruitment programme with any anti-maksiat programme and voila! Everytime GROs are caught in raids, don't put them in jail or summon them, make them do what they are born to do: Serve.
Punish them by forcing them to attend hostess courses and become train operators for a year or two.
Imagine a typical scenario in a KTM train... without a hot operator.
