Usually I do the same also...
Treat it as suay to pick up this kind of pax but also cannot
just let him go like that...

I will do more, cos I have time mah, crown no need so much rental,
2 hrs only, all rental covered liao..lols. I make sure my pax is
ok, then drive off. Once I called police, when police arrive, the
drunkard woman woke up, but still gong gong, tipsy, police asked me
(SMLJ) what happen uncle?, I said nothing, just now the pax cannot
wake up, boarding time told me the street, but dunno which block or
condos or units?? Now she is awake, can ask liao.
Police faces was like knnnccb taxi uncle, play with us ar?
...lols
Female pax later told me her address, on the way, keep saying
sorry sorry for troubling me, I told her, waste my time leh,
actually I use to earn $XXX but because of you become $XX, then
later she give me good tips..huat ar!
