Paul hatches a plan to catch Ruby and co drinking his whiskey in Friday's Fair City on RTÉ One and the RTÉ Player.
It works.
As Ruby replaces the whiskey with water in Paul's kitchen, in walks the man himself.
"Turn that off and get the hell out of here now before I call the police! Move!" roars Paul as Ruby's pals scarper.
As Ruby makes a beeline for the door, Paul stops her.
"Not you," he says.
