Sevi-yawn?

On a recent trip to Sevilla, I got chatting to a barman who appeared to be familiar with Welsh naming conventions.

Here's how the conversation didn't go (the original was in Spanish, so it's true!)...

Barman: So where are you from then?
Me: North Wales, in the UK.
Barman: Ah nice, my nephew goes to university in Cardiff.
Me: Good choice! That's in the south though.
Barman: I see. So if you're from Wales, your name must be Jones then?
Me: Ha ha, close! It's Williams.
Barman: Ha ha. Do you want another beer?
Me: Of course...
