πŸ˜ƒ: When three professors are seated in a restaurant, the hostess asks them: β€œDoes everyone want coffee?” The first
professor says: β€œI do not know.” The second professor
then says: β€œI do not know.” Finally, the third professor
says: β€œNo, not everyone wants coffee.” The hostess comes
back and gives coffee to the professors who want it. How
did she figure out who wanted coffee?
πŸ€–: This is a classic lateral thinking puzzle that requires a bit of creative reasoning. Here's how the hostess figured out who wanted coffee:

The first professor said "I don't know," which means they didn't have an opinion either way.

The second professor also said "I don't know," which means they were uncertain about their own desire for coffee.

However, when the third professor said "No, not everyone wants coffee," they were expressing a definitive opinion. By contrast, the other two professors were unsure or neutral, so the hostess inferred that only the third professor actually wanted coffee.
