Another Casualty of the Drought

My brother-in-law has said that he suspects the car wash cartel is
behind the drought. He means, of course, that the new water
restrictions favor commercial car washes because citizens are no longer allowed to wash their cars at home.

I think he may have a point even though I understand the argument that commercial car washes recycle their water. But really, don't we all recycle to a certain degree.

I mean if I wash my car in the driveway and the runoff makes it to a nearby creek, don't the fish benefit. Even if their eyes are burning as a result of the harsh chemicals in the car soap, isn't there a net positive effect to having more water in the stream?
