Madam, - I recently went on holidays to Mallorca, where it is inadvisable to drink the tap water. A five-litre bottle of water costs €1.30 in the supermarket.
Today I paid €2.30 for 250 mls of water in a well-known Dublin department store cafe.
For 20 times less water I paid €1 more.
Can anyone explain this? - Yours, etc.,
MARIE-CLAIRE WALSH, Donadea, Naas, Co Kildare.
