You don't necessarily have to prove that the customer did it, authorized it or benefited from it. While that would greatly help, just ask yourself if you have a defendable case.
The ATM was frequented by the customer.
It was done at a time when he wasn't at work.
His story changed and on the 5 transactions, we saw him in 2, then he said it was the other 3 he meant.
None of these facts is conclusive, but combined they could be justification for denial, in my opinion. Opinions will vary. I think this is reasonable. Seeing in the file that "my gut tells me he did this", doesn't cut it, especially if the denial rate of claims seems unreasonable.
Glad the reference material helped.
