Yes despite MrDoodles checking with his rod when I visited him I found the same one as you show all bunged up with twigs and leaves. So bad in fact that when pushing it through it pulled the drain tube off it's seat. It was a bit of a bear to pull back and re-seat
.
There was not water in there it was all dry in mine so I cleared out all the loose stuff I could find and reach so it cannot wash down and block the drain when it rains.
