Why though?!?

Why does the clinic have to be held at the school? Can’t they just provide a number instead of having to do it in the bathrooms? I think that would be much better because 1: it would be more time efficient so MC isn’t late to anything and 2: it would make it so Groff won’t be pissed at the clinic being held on campus. Yes I know it’s the game and adds to the plot I’m just saying
