You are going to work in your car. On the way, you stop at a red trafic light. And then, people come up with bottle of so called cleading product and a scrapper, and offer you to clean (or, more accurately, dirty) your windshield for a coin. Congratulations! You just fell prey to a Trafic Light Ambush. This trope is not restricted to windshield "cleaners", but also include all similar panhandling (Selling flowers at the trafic lights...)
ExamplesWeb Comics: Western Animation:
- Family Guy's earliest backstory for Brian had him meeting Peter by doing this to him, prior to Negative Continuity kicking in. Brian dirtied up Peter's window, and when Peter didn't have any money to pay him, he offered to bring Brian home for dinner with Lois and the family.
- Homeless people are commonly believed to do this.
