A branch of Tesco in Wales has been accused of “promising more than it can deliver” after a mistake in the Welsh translation of “free cash withdrawals” meant it ended up offering a “free erection”.

Aberystwyth councillor Ceredig Davies said the new cash machine put up this morning at a Tesco Express was the topic of all the “gossip around town this lunchtime”, with the error immediately noticeable to Welsh speakers.

He later went down to see for himself, and posted a picture on Facebook with the caption: “’Codiad am Ddim’ translates colloquially as ‘Free Erection’.”

Mr Davies said: “We’re accustomed to people making an effort to consider the Welsh language but not checking it properly. We come across plenty of examples – but few are as entertaining as this.

“10 out of 10 to Tesco for making the effort to have signs up in the Welsh language, but it perhaps would have served them better to check it with a Welsh speaker beforehand.”

A Welsh-speaking source told The Independent a more appropriate wording would have been “Codi arian am ddim”, literally translating as “raise money for free” – and while the unfortunate error has received a great deal of attention from locals, Mr Davies insisted they were only “having a laugh” at Tesco’s expense.

“People weren’t angry at the mistake - just amused,” he said. “I think the Welsh have a strong enough sense of humour for that.”

Sadly for those who might want to see the sign for themselves, a spokesperson for Tesco said the sign had now been removed.
