Automatic: you type nothing
One tap. Yafta picks a dish from your menu, shoots it, writes the caption. For the days you want a post and no decisions.
2
Composed: you choose
Three steps: the dish, the discount if any, and the look. When you type a discount: a bare number means pounds, a number with % means a percentage. What you type is what gets computed, and you see the final price as you type it.

Chat: say it your way
Like telling a staff member: a post for the falafel, ten off, through the weekend. It knows your dishes from your menu, and only does what you actually said.

All three read from the same library you set up.
