Although we are an increasingly obese society, it seems unlikely that anyone would be willing to wear this apparatus to Burger King or even outside of the house.
The first thing I thought of was this must be an accessory for use while reading "Fifty Shades of Grey". I really wish that there had been an infomercial selling this item as it would have been fun to watch people wearing the mask from the Hannibal Lecter collection! There is a link to the patent that can be viewed as a PDF here. Silence of the Lambs anyone?
