At the sound of the siren's going off Mel's head whipped around as the next client arrived, she flicked the button to quieten the alarm and looked at his very tall guy.  The siren was a metal detector,  and it generally only went off when clients walked in with their own handcuffs and sometimes car keys set it off.  "Erm Mr Bishop?" she enquired and she placed a white box the size of a shoe box on the reception desk "Can you please removed any metal objects you have in your possession into here please."
