Bring you own bag or box!
And if the staff at your favorite shop isn’t allowed to use your box, contact the management, send them an email. Ask them to change!
This is the sign which is now at Vollcorner. You can put your box on this tray, they are allowed to take the tray behind the counter and can then fill and weigh all your items in it. And/or contact your local authorities, in case they don’t grant this permission to your favorite shop.
You are the customer, you are a citizen, you can change the world!
And again: Apart from the environmental aspect, remember that it’s YOUR money, all the packaging is paid by you, and you also have to pay for the disposal at your home, too. Let’s better invest that money in more quality of the food!
