_NoK_
Look at it this way, depending upon postal code, you may have your bins emptied once a week or once a fortnight and over Xmas some bins in some postal codes will not be emptied for one month.
That surely is filth in any language.
I accept this I live on an Island and it is easier to organize, but our bins are emptied every day.
I cannot speak for bin emptying on Mainland Spain, perhaps NoMercy might help.
Clearly I am not referring to ALL people in the UK......but it has it's fair share.
