Keep cups

Sir, – Unlike Paul McDermott (Letters, April 10th), I search out the businesses that encourage the use of a “keep cup”. I bring it wherever I can, even on my bike spins, and thus obviate the extra cost of the disposable cup. This also avoids the collection of tons of throwaway waste, much of it ending up as litter on our roads. The Government should have a mandatory scheme for all businesses, as promised years ago. – Yours, etc,

DONAL DEERING,

Kilkenny.
