About a year ago, I spotted at my local supermarket an airwick automatic air freshener unit. It cost about $10 and I bought it right away thinking that it could be used to keep our toilet smelling nice and fresh and limit the amount of matches that are chucked in there to keep it from stinking the house out. So I arrived home from the shops with the brand new $10 automatic air freshener under my arm. And, predictably, my Mum wasn’t happy about me spending money on robotic air fresheners. I ended up having to pay for it myself. Oh well. It was still cool.
