I hate these leaflets, and I don’t understand why it is so popular. A person puts a sales leaflet under parked car’s windscreen wipers in the hope that it will drum up business.
However, what actually happens is that it annoys the car owner — they have to scrape the wet paper that has stuck to the glass. They cannot drive away and use their windscreen wipers until this job is done.
It is especially bad on an expensive car, and it can reveal to a thief, for example, how long the car has been parked there.
Thing are definitely getting worse!
