Samuel Powell spotted this neatly penned notice at Kentish Town London Underground station this morning.
Wonder if it was using the Rexley-Ruff rules to get there?
Update - Here's what happened to the dog. He was found by Rosy who said in the comments "My boyfriend and I were in fact holding the dog! We ended up taking him to work with us as Mornington Crescent station would have had to close its doors if it took on the responsibility of looking after a dog for a couple of hours due to staff shortages. We named the dog Frank, fed him sausages and gave him lots of attention! He was reunited with his rightful owner a few hours later. Frank had an eventful morning and everyone misses him at the office!"
