Are u sure u really want to do that in sg? You'll probably be
fined...
for littering. If you're lucky. Or you may also be fined for
vandalism of public property. But wait, the damage you caused may
create a problem for the trains, better add one more charge for
endangerment. Or better yet, just make it killer litter. Oh, and
don't mess up the doors in the meanwhile, you wouldn't want to get
them stuck - chewing gum fine. And I'm quite sure your act's going
to be caught on security camera. That's fine for accessory to
producing obscene video. And don't you dare die on the tracks, I'm
quite sure there's a fine for suicide too. And it's probably also
littering. Fine. Causing disruption to public transport? Fine. Oo..
and you really don't want to get started on the commotion after
that... illegal gathering, public nuisance, voicing of public
opinion...
