Ask HN: Feedback on text-based food delivery concept?

Here's how it would work:

1) Receive a text by 5pm each day with the day's 2 menu options (1 veg, 1 non-veg) 2) Text back if you want food (which option & quantity) by 6pm 3) Get it delivered by 7pm (first time you order, card + delivery info recorded)

Thoughts?
