Back in Ye Olden Days, we probably had the first web interface to order pizza. "We" had been a long-established computer nerd meeting, and this pizza service that normally was closed on Sundays actually opened just for us on that weekend just for the occasion. We had an internal web page to order and organize orders of pizza. But of course, the order did not go out electronically - when our web app saw the need to place the order, is simply sent a fax ;-)
