Sample A — Why leftover exists (it is not a moral failure)
When to use: You are about to bin food and feel like you guessed the rush wrong.
Leftover at close is not because the cook is bad at guessing. It is how fresh food works. You cook for the rush. You cannot perfectly predict rain, a football match, a delayed train, a school holiday, or that one dish going viral at lunch. You over-produce a little so you are not empty at peak. Then close arrives and the extra is still there. Throwing it away has a cost. Discounting on a handwritten sign only works if the right person is already staring at the stall. Boosting a post to “people who like food” hits a thousand strangers and none of the twenty still on the street. The waste is the last tray and the last walkers never meet.
