"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"

This quote by Emo Philips is a humorous take on the concept of distributing something free of charge in order to attract customers. By offering the initial glass of lemonade totally free, he is suggesting that consumers will be more likely to purchase the 2nd glass, which has the "antidote". This could be taken a metaphor for exactly how organizations usually supply totally free examples or price cuts in order to urge customers to purchase their items. The quote also suggests that the 2nd glass of lemonade is more valuable than the very first, as it has the "remedy" which might be taken something that will provide a benefit or remedy to the client. On the whole, this quote is a humorous method of highlighting the relevance of using something of value in order to draw in clients.
