How do you update stock in real time on a photo menu?

When it sells out, the whole card is hidden, photo and video included, before the next ticket. Striking the text is not enough if the image still invites the order. Leave someone on the shift the gesture to hide the card, not only the person who uploaded the photos. At a Madrid lunch the rice runs out and the rice video stays on the menu until night. The card disappears with its photo and its clip on that signal from the pass.
