Since you can only drive on limited hours and if you do HG, filtering the big fares is a high risk game unless you've found a place with constant low fares, else what you could do is only drive during UP & MP where grab will throw you high fares and you could collect only those and forget the ikan bilis.

if you do flexi, often times you'll only get ikan bilis but since the minimum AR is 30% you could always filter those out for bigger fares but then again location matters.

Where do you live?

only if your air con is cold enough, so the temperature will limit the growth of those bacteria create smell.

Today i take off to go to Brickfields blind massage therapist my back hurts like mad couldn't sleep properly last night almost screaming just to shift from one side to another, hopefully those blind specialist can fix my back so i can get back driving tomorrow onwards.
Take care of yourself guys don't overwork, rest well.
