Why does the girls bathroom have no toilet paper during seventh period?

The lack of toilet paper is ridiculous, girls use more toilet paper than men for obvious reasons and if it’s not obvious it’s because we are more hygienic. Just kidding, but seriously, why is it so hard to keep toilet paper stocked? I have to use the restroom during period seven sometimes because I have athletics and it is so annoying to be running around trying to find the one stall that has toilet paper. I do not think it is hard to check the bathrooms at lunch so we can have the supplies we need for a productive life.
