I never said that there shouldn't be a reasonable policy on limiting bathroom breaks. In fact, I suggested at least one. But I believe that this whole "taking excessive breaks" thing is being exaggerated here. And this policy really doesn't in itself limit all bathroom breaks to all students, nor in the correct way. Students who care more about breaks during their school time could easily earn and use their money just on bathroom breaks. Children do not think ahead about these sorts of things. And this sort of thing is not going to make children more likely to spend their money "wisely", nor should it be done.
