I explained what a basis point is to the project manager about a dozen times and showed her how they work. She's supposed to have completed calculus, so it shouldn't be hard for her.
She still doesn't understand them and is now insisting that all basis point figures be put in terms of percentages. She's too lazy to move a decimal point 2 places a few times to do her work. That means I have to change 12 tables because she really is this stupid and lazy.
