We have this problem too with a soap dispenser. (They are for washing your hands before you dry them.) The one of the right never works. I mean never. Like you, I always try to get soap from it. I have thought about this a lot actually and I think I have figured it out. Of course, me trying to use the soap dispenser even though I know it won't work is, in itself the definition of insanity let us just focus on the dispenser not working. The custodian will enter the men's room and open all of the soap dispenders and paper towel dispensers and see that they are full and think nothing of it, or they will refill what is needed. If the soap dispenser simply does not work it will always appear to be full and no action is necessary. These people probably mindlessly do their jobs and don't care enough to inform facilities that it is broken. I mean that would mean more work, right? By the way, I started a thread that this could fit into. Have you read it? It is quite something.
