Does a gift card pay the delivery fee too, or only the food?

The whole total. On the summary step of checkout the customer types the code into Gift card code and presses Use, and the card pays as much of the total as it can hold. The total is worked out first with the food, the delivery fee and any coupon or reward already in it, so the card is not limited to the dishes. What is left to pay, if anything, is collected by the rider in cash or on the card machine. It works the same on the Charge screen at the counter: pay part on the card and the rest another way on the same sale.
