““You wouldn’t happen to know...” (This throws down a challenge, which makes people want to prove you wrong.) “... just one person...” (Just one, because it’s reasonable and seems a simple ask, and they’re more likely to think of someone by name.) “... someone who, ust like you...” (This has the person narrowing down the options and gives you more of the right prospects, plus it pays a subtle compliment.) “... would benefit from...” And then emphasize the specific benefit or positive experience they have just thanked you for. Then... shut up! People say thank you when they feel they owe you something.””
