The fee problem, stated honestly
A delivery order carries a delivery charge, a service fee, sometimes a small-order fee, and a tip. Depending on the order that can add a substantial fraction on top of the food price.
Credit covers the total, which sounds generous until you notice it means the credit is buying fees as well as dinner. Treat a delivery credit as worth noticeably less in food than the same amount spent in a restaurant.
If you want the gift to cover a specific meal, add roughly a third and say it is for the whole order.
Shared wallet with rides
In many markets the credit sits in a single balance shared with the ride-hailing side of the app. That is genuinely useful — an unused food balance becomes a ride home — but it also means the money can quietly go somewhere the giver did not intend.
Worth a sentence to the recipient about what you meant it for.
Region and city
Credit is country-specific, and the service only operates in particular cities within a country. Someone in a small town may have very few restaurants listed, or none.
Check the recipient's area actually has coverage. A credit with three restaurants available is a worse gift than a card for a shop they can walk to.
Minimums and availability
Some restaurants set order minimums. Late at night the choice narrows sharply. Neither is a dealbreaker but both shape what the gift is actually worth.
Who it suits
Students, people working shifts, anyone recovering from illness, new parents. Less good for someone who cooks and rarely orders in.
Asking for one
