Hire solution for trolley problem

Local supermarkets could hire trolleys to people (on a weekly or monthly basis) and have these trolleys clearly marked.

The people who wish to use this service could then take the trolleys home, and use them repeatedly without fear of penalty.

The hire fee could also help to cover the cost of retrieval if necessary.

These customers are frequently those who live very close the supermarkets, and are making an environmentally sound action by not using a car for a short journey.
