waste paper collection for toilet paper exchange
A service where old newspapers, magazines, or cardboard are collected and exchanged for toilet paper or tissues. Common in residential areas; often announced by loudspeaker trucks.
The waste paper collection truck came, so I put out the old newspapers.
In some areas, waste paper collection for toilet paper exchange is still practiced.
