A luxury apartment building in the Lozenets quarter in Sofia. A solid-looking businessman is pushing the entrance door from the inside trying to go out.
"You need to pull, sir!" the doorman says.
"But it says "PUSH" on the door!"
"That's right, sir. The gentleman living on the second floor came up with that. This allows him to catch up with his wife's lovers when he chases them," explains the nice doorman.
