Difficult to describe, but here goes…
Big industrial bin (with lid and a smaller domestic bin sized aperture in it). I couldn’t get the boxes through the hole and assumed it was full so I climbed on the lid and leant against the boxes. The box sides gave away and, instead of them slowly pushing down on top of a pile of rubbish, shot straight down into a freshly emptied bin (but still rank with the smell of fish as it was a chippy bin). I followed the box into the bin and just managed to catch my legs on the lip, so there I was, hanging upside down in a bin.
I couldn’t get out but an old lady who saw it happen came across, climbed up and helped me out.
Ohh joy – still makes me giggle now, some 20 or so years later 🙂
