Sir – We like the green sacks! Last week we left out two excessively full green sacks as we just hadn’t had the time to cut everything up and put it neatly inside the sack. We had lost a very special trowel and each sack had been emptied and gone through about three times, the garden had been searched and everywhere else.

Imagine our delight when leaving the house early the next morning. Not only had the two sacks been completly emptied but the missing trowel was sitting neatly on top of the folded bags.

Even though weekly collections of food waste would be desirable, the recycling service works well.
