I think it was in a different pub where the landlord had a big problem when a dog was run over by a tram outside his door late one night – the poor animal had his tail cut off and died from loss of blood.
Every night at midnight, the ghost of the dog came back to look for his tail, but couldn’t find it, so just sat there howling until 1am.
When a barman asked his boss why he didn’t do anything about this, his reply was, very simply, “My license doesn’t let me re-tail spirits after 11pm”.
