Dude. We have a guy who is the custodian. He changes the water jugs at the office and does other stuff. But he doesn't change the water jugs. Now he just waits. Because if he waits long enough, either I will do it out of my own need for water, or someone else will ask me to do it because he is not around.
Fine. He's like, 70. And he recently had hip surgery. And he doesn't really wait for me to do it, it's just that I don't have the heart to ask him to change it, so I do it myself. But I only notice when I'm thirsty. And when you're thirsty, you don't want to change a water cooler. But I do. Because I'm not going to drink out of the sink. Not anymore. Not after last time.
