This just means Crapita 'internal' accountants are very good at their job of hiding the loot.
Given that most of what they do is
a) Hold meetings
b) Make Powerpoints
c) Email Powerpoints
IOW they move nothing physical, apart from a consultants backside (unlike a supermarket, where pretty much everything is a physical object), who if they are any good might well be actually a sub contractor (although they will be under strict orders not to say so).
The whiff of the farmyard was very strong in the original statement.
