It’s an American agency called Wundermann.
Apparently, one day the owner flew in to visit his agency.
He was a big, brash New Yorker.
He drove straight into the car park below the building.
The gruff cockney parking attendant stopped him.
He said, ‘Where you going, guv?’
The American was indignant.
He said, ‘I’m parking, of course.’
The parking attendant said, ‘You gotta permit?’
The American said, ‘No.’
The parking attendant said, ‘Then you ain’t parking here.’
The American was outraged.
He said, ‘Do you know who I am?’
The parking attendant shook his head and said, ‘No.’
The American got out of the car, raised himself up to his full height, tapped his chest and said, ‘I’m Wundermann.’
The parking attendant said, ‘I don’t care if you’re fucking Superman. You ain’t parking here’
