Oh this was long time ago, I did not receive any.
I did a few times, noticeable experience are, one very near the bus stop directly outside the FLS boarding and alighting took around 3 minutes at best, and one is slightly in front near the traffic lights where an old couple flag my taxi, I just stop by the side and allow them boarding.

Whole process of boarding took around 3-5 minutes?
I'm unsure if they see me as a commercial taxi driver so they are more flexible?

But I do see other private cars do the same before.

However I cannot vouch for them if they got any penalty from the action.
Hope it helps.
