There are consequences for bad financial decisions.

Clearly the first was paying this freak of a teacher to have access to kids.

[Robe]

Having once been a high school teacher, rest room management is left up to the individual teacher. Some give out passes which are initialed each time the kid wants to got to the RR, you may decide 12 14 times a year is suitable.
Some teachers have no limits, and some have an “emergency Only” policy.
Me, I had an old toilet seat painted pink with m name and room on it. Students had the carry with them to the RR.
It was an effective deterrent.
However I never refused a student that declared an “Emergency”
