My echo picked up something being said on the TV and suddenly blurted out "do you want me to order your dog food?" and waited for a confirmation. Surprised, I said No and the order attempt was cancelled. Straight after, I disabled the voice ordering. :)
Oh, we don't even have a dog.
I can see someone in advert land rubbing their hands together with glee at the prospect of their new TV ad...
"You too can have the great Widget in your house. And remember you can order through Alexa... Order Widget NOW!.... Yes Don't delay. It will be loved by you and your family".
Honest judge, I didn't realise that would happen.
