Smoking in the bathrooms

I was actually thinking about this just the other day. I just have come up with, as much as I would like everybody to have manners some people just don't care about others if they did than most students wouldn't smoke in the bathrooms. I really don't have a solution except to have somebody stay in the concourse bathrooms constantly, because if you can't do anything to the student unless you catch them than stay in the bathroom or sit outside the bathroom grading papers or something and when a student comes to go into the bathroom just go in there to make sure they don't smoke. As much as teachers say that they are going to lock each bathrooms on each halls they don't so that's why some students get a way with it a lot. Coffee High just needs to tighten up a lot more in my opinion.
