Rampage

It's a warm, summer Tuesday afternoon. You and your coworkers step out of the office building on your 2:00 break to get some outside air, something different from the air conditioned office.
While enjoying the summertime city view from the sidewalk, a car can suddenly be seen some distance down the road, racing at high speed in your direction. While this happens, some fifty people emerge from the office building next door and stand on the sidewalk. As the racing car comes closer, you can finally see the vehicle’s make and model.
"I don't believe it!" you exclaim. "What???"
The car is a classic 1980s Dodge Rampage, one of those cute car/pickup hybrids that resembled a miniature El Cameno. They didn't stay in production very long, and it's been a some decades since you've seen one of them out on the road.
There it goes, racing past the office building. The driver honks the horn, and the fifty or so office workers from next door cheer and wave.
"Jeez!" you exclaim. "Why the heck is he driving so fast? Is the driver a maniac?"
The driver slams on the car's brakes and does a sharp U-turn about a block down the road and then races back in your direction. It's almost frightening. And the engine sounds like an Indy-500 race car at open throttle.
Some hundred feet from the office, the driver slams on the Rampage's brakes which brings the car to a screeching halt in front of the office next door. It is then that the fifty or so people rush over with Styrofoam cups and dip them into the open pickup of the Rampage. For the first time you realize that the car had been transporting water in the open back.
The office workers gulp the water down from their cups. They are very thirsty, and many of them dip their cups into the pickup of the Rampage two or three times more.
Curious, you walk over and ask someone who had just finished a cup of water, "What's this all about?"
"Oh, we're having trouble with our water, and it hasn't been fixed.” he explains. “We haven't had any water all day, and we called to have some delivered as an emergency.”
"Interesting..." you remark. "That's definitely an interesting way to have your water delivered."
But then you wonder how sanitary the water is, being that it was transported in an open pickup and probably contaminated by the city's dust and dirt.
