I am one of those people who leaves empting my bin till the very last minute. In fact thinking about it, the rubbish literally has to be spilling out of the bin on to the floor surrounding the bin to prompt me to run to my supply of rubbish bags in my handy kitchen draw and pull one out.
Why do I/we do it? Laziness most probably but also somewhere in the back of our heads we probably think its going to empty itself or more likely that this infrequent emptying is less work and more economic – this is a false economy.
By this time an old banana skin or stale biscuit would have grown a world all of it’s own, and the bin is so full and heavy that when emptied this is likely to result in a bag getting split and a horrible mess all over the floor.
