A Dublin pub has started charging customers for tap water.
Diceys Bar on Harcourt Street has introduced a charge of 20c for a pint of tap water.
Last night a staff member in the bar told the Herald that the fee on water had been introduced "about two weeks ago".
While the 20c price did not appear on a receipt in the venue last night the staff member said "it's in the system".
Customers yesterday and on Tuesday reported that they were being charged for tap water during the day in the bar, much to their surprise.
"I don't know if it is a day or a night-time charge yet," said the staff member.
The move is the latest twist in the water saga as metres are being installed across homes in Ireland.
People now have until the end of the month to register with Irish Water.
However, it is homes that are in for the shock as pubs, hotels and restaurants already pay commercial rates for their water supply and have done so for decades.
Adrian Cummins of the Restaurant Association of Ireland (RAI) said that he has not heard of any dining establishments charging for water.
"We wouldn't be proposing that restaurants would introduce a charge for tap water," said the RAI chief.
"What I have heard of is charge for filtered water," he added.
Some restaurants and cafes around the city are offering customers bottles of filtered water for a price of around €2, and some of the businesses give that money to a chosen charity.
The owner will buy in a filtering machine and use it with their normal water supply and bottle it themselves for customers.
The news of Diceys charging for their iced water emerged yesterday after a customer got his lunch there along with a pint of iced water.
Jarrod Bromley tweeted a photo of his receipt showing a bill of €6.45, €6.25 of which was for his lunch and 20c was for a "pint of ice water," as printed on the bill.
He had been there last week and was not charged for tap water.
Mr Bromley said he asked the bar man was he "joking", but he was told it was not a joke.
Attempts to contact management at Diceys yesterday to ask about the new policy behind the charge were unsuccessful.
Up until the introduction of water charges only non-domestic users paid for their supply.
Offices, shops, schools, churches, pubs, restaurants and hotels all pay a fee for the supply and discharge of water into the public drainage system.
