If you are going to worry about things, first read each of the following:
Then examine whether or not there is anything you can do about the situation to correct or improve it. If you can, and it is in the realm of your responsibility, then do it. If it belongs to someone else, you have two choices: alert the person about it, with the expectation that they will do what is required, or, don't let them know.
