This unit sits below the counter between the sink and the edge. Only a slot shows when not in use.
Like a roll of paper towels, this under-counter mounted unit dispenses an apron that is donned by pulling the small exposed tab and putting the collar end over your head while pulling up from the roll.
The apron only detaches from the roll when the user tears their used apron from the roll, thus providing total coverage while preventing splash and bits from falling to the floor.
Like the tissue covers for toilets, but splashproof and much more attractive, they are disposable and cheap, with refills for the under-counter roll holder, which is hidden until the next apron tab is pulled.
[If you've ever 'picked' boiled crab you are familiar with the bib provided for crab and lobster.]
