Dam drunk or need ppl to carry of course don't take. Why ask for
trouble?
Those not sure type u can also make them do a "walk test".
How?
Stop more than one car length infront of them. Observe them from
the rear view mirror.
If they can't walk properly. Zoom off lah. Let them smell
exhaust diesel to freshen up.
I kena once when a pax flag, I stop. He walk back and help his
drunk friend, I quickly step on the accelerator. I think he will
knnbccb behind my vehicle.
