For some reason, the upper decks of the 211 (even in Winter) are

I think i identified a contributory cause this afternoon on a no 30 - on
the upper deck the heating was on. I asked the driver - he seemed
clueless.

Loads of buses have the heating on all year round, regardless of how hot
it is. I really don't know why, unless it's just driver
forgetfulness/stupidity/error/malice.
