Got told to take a 10 minute break by my line manager, because he thought I was getting frustrated and needed a breather.
For something like the 4th time in a row , after sending a guy a data set with a "here is a mass of data, please tick "Y" in the column "in scope" so we know which to actually migrate for you, the guy has returned a completely different file with all the data structured completely different ways, marked with his own unique variants of "keep" "don't keep" "yes" "obsolete this"....
