make HoS non exclusive to mentors

[Drago156]

Honestly, I feel Fridays being days where mentors have access to HoS is the best, because it allows mentors to have a day to test the job out every week and allows them to consider applying for HoS, however, making it open to ALL mentors EVERY day would be a shit idea, just because someone is a mentor doesn't mean they are A. Robust and a competent security personnel B. They are necessarily trustworthy or able to handle the role without being completely strict and kinda un-fun and C. Not shit.
