Feeder and intra-town services all charge 63 cents using ezlink
cards. (if not making a transfer)
I also don't see the need of scanning the card on these services
when alighting, because the fare deducted when scanning at entry is
63 cents already, unless.....

I think it's for a good habit, because some may forgot to scan when
alighting from trunk services, if they have a habit of not scanning
when alighting from feeder and intra-town services.
