A food truck has no tables to map and no room to oversee, but it has exactly the same underlying problem as a restaurant during the rush: too many orders, too little time to write them well. With a single person often handling both till and kitchen, a badly written or lost order is a customer waiting without knowing why, in a queue that keeps growing.
GrazieChef treats every food truck order the way it already treats takeaway for a restaurant: a session without a table, identified by a name or a number, with its own bill and status — in progress, ready, served — always visible. No floor map needed to know how far along each order in the queue is.
The digital QR code menu is especially useful for anyone working out of a truck: when an ingredient runs out or the dish of the day changes, you update the menu once instead of reprinting a sign. Whoever's in the queue sees it updated on their phone, before they even order.
