Next collection... (Saturday?)

Another long and busy day of work.  I stopped at lunchtime to eat, watch an episode of Countdown and take some cards to the postbox.  Bit puzzled by the 'SAT' plaque - can it really be they won't collect until then?  I can't see anything to say that post collections are reduced, but I guess I can believe it.

Crap photo, but it was just starting to tip it down at this point, and I was holding an umbrella.  Dropped my phone just after this - very lucky not to crack the screen, but dinged another corner :/
