Who's Emptying the Trash?

Didn't know which thread to put this post under, so, made a new one. This centers around the question: Who's emptying the trash?

The trash pick-up guys came and went this past week to pick up trash twice and recyclables once, yet there was no trash pick-up at one of the stumps at Bath House #2, and the other one was, yet NO new trash liner was put in one of the stumps.  This is not the first time this has happened; sometimes there are no new trash liners put in either stump. Also noticed is how the trash at this bath house has piled up in these two stumps and was not emptied until after it was almost overflowing--this has also happened numerous times--both also at the Dog Run trash stump and the one by the newspaper can. These occurrences of overflowing trash were noted during this past summer, and has continued to be a problem.     

This begs the question: What are our employees doing that precludes them from their regular duty of taking the trash out of common area stumps and having ready for the trash guys to pick it up?
