The Irish Postal system - An Post

Liam Stewart is one of our biggest supporters, advisers and friends of Wells for Zoe.
He lives in Cavan and Mary sent him this letter yesterday, without an address!!
It arrived bang on time this morning, so he sent the pic to prove it.
Do we have amazing postmen or what?
We all thought that everyone knows Liam, but now we're sure.
Five star service and the brain that got this one spot on.
Thanks guys

Hi Mary and John,
Thank you for the acknowledgement which I received today.
I knew Ireland was small but didn't think it was that small that the attached
address would work!
