Brian Gaff formulated on Thursday :
apparently the newer vehicles can only handle this size of bins these days.
Its about time these waste collecting outfits put their heads together and
got a standard sorted out.

That is a standard isn't it? All the bin sizes are the same height, to
suit mechanical emptying, but their width/capacity varies. The only way
they could accept smaller than the standard, is by making the bins
narrower, which would make them unstable.
