What works best?

We have been nicely asking supermarkets and producers to fix this excess packaging problem for DECADES, petitions, direct emails, customer feedback etc, many of us boycott plastic products, yet the problem GETS WORSE! How can we get shops to listen?
Jackie often goes to to Aldi. She unwraps her shopping and leaved the plastic packaging in the shop to highlight the excess single use plastic created by the food industry. The manager has spoken to her and she has explained her reasons for doing this. Jacki asked him to contact Aldi head office to request they review their policy on the use of plastic and he promised to do this.
What do you think works best?
