Bizarrely, on some London Central buses on the top-deck the back three
rows (i.e. the rear-most forward facing, the accompanying backward
facing and then the next forward facing rows) are plastic seats.

If you check the floor, you'll see holes that allow water (or other
liquids) to drain out.

Now I presume people at night have a tendancy to throw up, or urinate
on the bus, hence the plastic seats and the drains. Or, perhaps it is
so the bus company can literally jet wash them in the depot. Or, both!

ISTR that some have stuck on fabric and, IME, aren't that uncomfortable
even without any real padding. Probably only good for a 10-20 minute
journey though.
