Bunnings sell an enormous range of useful goodies, including rubbish bags and tools to help you pick up rubbish. It's a pity that they don't seem to make much use of them at the Lidcombe store. The store carpark backs onto the motorway, and a great deal of rubbish has built up against the boundary fence. Someone is cutting the grass along the fence, so they must know it is there - but no one is doing anything about it.
They're probably using a contractor to cut the grass, and the contractor doesn't see it as their job to report the huge pile of rubbish along the fence. Or the contractor has been engaged by the landlord, who doesn't care. Whichever way you look at it, it's not good for Bunnings image as a good corporate citizen.
I've used the feedback form on the Bunnings website to ask them to clean this up.
