Surely this is not really worth police time. Cant have given him anymore than a tenner more than he was owed surely? And if they did then its really the chip shops fault for not checking. Do you think maybe police want him for something else instead?
How do they know it was a con? The guy may have been genuinely convinced he was owed the change, plus, cctv is not admissable,....... why am i defending customers?
Well it is gaining money by deception, but is a bit OTT. He may have been innocent, thought he'd given over more money than he had, or the chippy could be lying.
he may be doing this regularly though as a con.
There are often people who try to do this by way of distracting and confusing staff into giving back more than they should in change.
Many a time when i ran the shops and even when i first started working saturday job there would be gangs of people trying this con.
Its rather clever and many staff have been caught out.
