I work in a management accounts department.
The most irritating come from our parent company in Europe and typically take the form of “we are seeing this number (sent on a screenshot so no chance of seeing any workings behind it), you are showing a different number – can you please explain the difference?”
Answer (I would like to give) “so you are saying explain the difference between two numbers, one of which I cannot possibly know how it is derived – why don’t you do the explaining”.
The best example of this was when our FD spent a while trying to sort one of these problems (credit to him for trying) and then handed it on to me. I had a look at it for a few minutes then noticed that all the differences were exactly the same % of the number they shoudl have been. They were looking at a figure they had converted into Euros agains the same figure from us in sterling.
That was twenty minutes of my life I won’t get back……………..
