"Unbelievable" or "Only in Wales"

Hi all!

Had to share this....

My father in law came to visit the other day and we had the "how's the rest of the family" updates. He began talking about my sister in law down in south wales and how her boyfriend had bought himself a motor bike as he's hoping to get a job sometime soon. He went on to tell us how the boyfriend had ridden the bike to the petrol station to fill it up. As he was going in to pay took his helmet off and noticed an "odd smell". Turns out he filled it up with diesel, I can kind of understand filling a car with the wrong fuel but a bike?? I'd like to say "kids today" but the guy is older than me.
