A Tesco ATM machine at the Aberystwyth store shocked people when they saw "codiad am ddim" plastered above them, meaning free erection.
Ceregig Davies, who snapped the mistake and shared it on Facebook, said that Tesco should have had it checked by an actual Welsh speaker before putting the signs on the machines, the Daily Star reported.
He said that anyone with a basic understanding of Welsh would never mistake the word "erection", for "cash" and he isn't sure how the company came up with it because anyone with a basic understanding of Welsh would know it is the wrong word.
