At my lemonade stand I used to give the first glass away free and charge five dollars for the second glass. The refill contained the antidote.

Our reading
An editorial interpretation.
The free first glass looks generous until the final sentence reveals that the paid refill contained an antidote. That reversal suggests the initial offer created the need for the second purchase. The joke turns a familiar lemonade stand into an absurdly sinister business arrangement.
