I have just spent 8 hours doing miniscule changes to a two page report as per client request. It’s an in-company client, so this time is not paid extra. All changes are barely visible (moving a title 2 px left or right, choosing a color that’s 3 points more saturated etc.) and all are purely subjective.
Best part? MAKING the two-pager from the ground-up took me 7 hours total.
