I volunteered to try to find some B&Bs in a particular village in Wales, before the internet, etc. I rang the post office, on the basis that they would have a good idea of what was going on.
"There's only two and neither of them do it all year"
"That's OK, can I have the addresses?"
"Jones, Main Street"
"And the other one?"
"Jones, Main Street"
At which point I laughed - "You can laugh! I have to deliver the bloody mail round here..."
