I've had two similar experiences. Years ago I bought some 85% absinthe from my local bottle shop. I was riding home on my longboard and the bag had a hole in it. I heard a smash and there was $110 in the gutter.

Recently I went shopping with my kids in their trailer pram. I bought a bit too much stuff and had to sit my lunch on top of everything else in the back storage section. My lunch slipped out the back but it didn't get too dirty so I rode home holding its paper bag myself
