That's one thing that annoys me. Supermarkets expect us to do our bit for the environment by using reusable bags, but they could do so much more than they do.

For instance, whenever I have used my own bag on the self checkout, the machine has called over a checkout operator to verify that I had my own bags. Frankly, the time wasted waiting for the operator to come over and verify this isn't worth the extra nectar points.

Another thing supermarkets could do is provide paper bags. Yes, these are more expensive but that can be recycled a lot more easily than plastic bags.

They could also allow us to re-use their old boxes. Instead, they prefer to sell them to other companies which, while it is profitable for them, is not particularly environment friendly as it involves trucks taking the cardboard to the plant for recycling.
