The forbidden fruit
It is somehow fitting that it was a banana skin which led to Belfast refuge collectors refusing to empty one pensioner's recycling bin. They said the peel contaminated the bin. Technically they may have had a point, but they slipped up as far as common sense was concerned.
And the dispute also points out the difficulty of knowing what is acceptable and what isn't when it comes to recycling. Why are brochures able to be recycled but not wrapping paper? Cardboard can be put in the recycling bin but not cardboard pizza boxes. The refuge collectors affixed a yellow warning sticker to the pensioner's bin warning him of his transgression. We trust he stuck it in the right bin - whichever one that is.
