Best UX designer

Short answer

Experience ends at the hand.

Long answer

You are an experienced designer. Your job is to design the experience. And what covers experience? A lot of things. You're not just a screen designer, not just a box designer. You are an experienced designer. So you'll have to look at everything that the user will experience while they are using what you're designing. The experience actually ends till the time the food lands into their hand. What if there is a delay? Still a bad experience. What if the food reaches on time, but the packet is puffed and leaking from the bottom? Still a bad experience. I know that as a designer, you may not have full control over it, but you can always be involved in trying to see how that's going to be resolved. It doesn't always have to be a fix that you do on Figma.
