This reminds me of what happened to Jynnelle when she was driving to my house.

The car in front of her was kicking dirt onto her windshield, and her window wipers weren't getting the dirt off. She pulled over and tried to get that little spray thingy to work, but she couldn't figure out how. A cop stops and asks if she needs help. They stand there for a while, trying to firgure out how to get the spray thingy to work. The cop says Jynnelle doesn't have any cleaner left. So she and Jynnelle go into the store and buy some, then they have to try and figure out how to get the cleaner into the car. After doing that for a while, finally some guy asks them if they need help. He does it for them, and all is well. Lol.
