Neighbour.
I recently had to access her shed. She has wall to wall storage boxes. Very neat. Very organised.
Except they are all free recycling boxes from the council. We all get one red one blue and one food caddy. She has about 10 of each.
I asked her and she said "oh you just to the collection point and the give you more". She's been to ALL the collection points and collected a set from each 
She's even using the food caddys to store dry pet food. She had no shame at all about it.
I can't work out if it's the councils own fault for not keeping any records of who collects or her fault for clearly stealing 
so she can have lovely neat stackable storage!
