Eric Trump sparked the ire of beer fans across the UK when he tried his hand at pulling a pint of ale.
Donald Trump’s son tried to pull the pint while he was on a “pub crawl” with his older brother, Donald Trump Jr. in the tiny Irish village of Doonbeg.
At a street party thrown in celebration of the president’s visit, Mr Trump’s two sons went from pub to pub posing for selfies, shaking hands and buying drinks for residents.
At one pub, Donald Trump Jr pulled a pint with an acceptable head on it.
But his brother’s effort to pull a pint of Smithwick’s Red Ale was branded an “absolute abomination”.
However Eric was unfased and was clearly enjoying his time behind the bar.
Hundreds of people took to social media to criticise the enormous foamy head on Eric Trump's effort. The foam filled around half the pint glass.
One Twitter User wrote: “Eric Trump would not survive one shift at the pubs and clubs of Yorkshire that taught me my craft.”
Another said: “Eric trumps pint of Guinness is the worst ever.”
Stephen Todd captioned his post: “Eric Trump is a clown, but this isn’t a poor pint. It’s simply impossible to pour a pint of Guinness with such a large head. The cream is stuck to the glass.”
“Eric Trump’s pint tells you everything you need to know.”
While the main protest for Trump's Irish visit is planned for Dublin on Thursday, it was the adoring locals in Doonbeg who outnumbered the demonstrators that greeted the U.S. president upon his arrival at Shannon Airport.
On Wednesday, Doonbeg residents decked the streets in American flags and bunting, crediting Mr Trump with securing local livelihoods after he bought the nearby gold resort in 2014.
It was a stark contrast to the mass protests that greeted Mr Trump in London and Portsmouth this week.
"Everywhere we look all we see is American flags with Irish flags. That's a beautiful thing ... It's so nice to see so thank you," Eric Trump told cheering crowds as he served pints from behind the bar at Tubridy's, one of five pubs the brothers visited in the space of an hour.
"God bless Donald Trump," was the response from a satisfied customer at one of the stops while another stood behind the pair's car waving a Trump flag as their motorcade returned to the five-star hotel.
"I was absolutely delighted. I got to shake Eric Trump's hand twice," said Martin Doyle, 28, a barman from neighbouring Limerick, draped in an American flag and a Trump sweatshirt.
"There is too much negativity ... In the grand scheme of things, there are a lot of people who wouldn't admit (supporting Trump)."
