What mistake do PDF-only photo menus make?

A PDF freezes the photo and the price in a file that on the phone opens late or sideways, and a sell-out cannot be hidden. It is not a table menu if the image cannot be pulled during service. Open the PDF on the terrace and see whether the first photo arrives before the table gives up. In the Madrid rush the file never gets past the cover and the floor recites from memory. The QR opens cards on which the photo is hidden when the dish runs out.
