Personally I think it's correct that people in their work attire should not be allowed into that splendid establishment,
what what what !
Assuming the manager, owners and staff on duty are all working, they should get their kit off and serve naked.
Also, your son should go round the back of the pub and 'make his own work' and then walk in saying "There's a blue
sports car outside with a broken windshield, anyone need it repaired"
