Really? Brain?

Walking out to lunch yesterday, and the delivery truck with our Company's bottled water delivery is out front.  I notice a massive puddle of water on one side.  Walking around, I see the driver standing with three large (the give 5 gallon water cooler type) bottles on their sides letting the water drain.  He looks at me and says, "cracked".  I'm guessing the bottles, although I could have just as easily guessed his brain.  Keep in mind, he is doing this three feet from the bank of plants alongside the building.  The exchange went something like this:

Him:  Cracked.
Me:  Don't you think it might be a little less wasteful to poor them into the plants right there, rather then down the parking lot?
Him:  Can't.
Me:  Why?
Him:  Against company policy.
Me:  Your company is against watering plants?
Him:  If the plants die, it would be our fault.
Me:  What's in your water that would cause the plants to die?
Him:  Nothing.
Me:  Then why not water them?
Him:  Oh.  All done.  Have a nice day.

This is why I need to be allowed to drink while at work.
