A combo is a deal, not a dish.
The margin at a counter is in the second item. It is worth being exact about where a combo actually comes from, because it is not where most people assume.
There is no combo SKU in the catalog, no bundle entity and no meal type — so a combo here is one of two things, and it is worth knowing which. Either it is a dish with required choice groups attached, a burger that cannot go into the cart until a side and a drink have been answered. Or it is a daily deal: scoped to one branch, on the weekdays you choose, between a start and an end time, targeting exactly one item or one whole category, in five shapes — percent off, amount off, buy X get Y, spend X get an item free, and buy X get an item free.
The shape that reads as a meal deal is the add-on. While the target item is in the cart, a named add-on is offered at a fixed price or at a percentage off its base price, capped at the quantity of the qualifying item, with the main item’s own discount optional — so the burger can stay at full price while the fries go to twenty rupees for anyone who bought one.
A deal can carry hours. The menu cannot. A branch can switch an item off, and a deal can run from four to seven, but there is no breakfast menu that closes at eleven and no late-night list that appears at ten — and a page that implied otherwise would be selling you something you would go looking for in week two.
