A man walks into a small café and orders a coffee. As he sits down, he notices a sign on the wall that says: **"Wi-Fi Password: Ask Staff."** So, naturally, he calls over the barista.
"Excuse me," he says, "what's the Wi-Fi password?"
The barista smiles and replies, "You’ll have to buy a coffee first."
The man holds up his steaming cup and says, "But I just bought one!"
The barista nods. "Oh, right! Sorry about that. The password is: *You’ll have to buy a coffee first.* All lowercase, no spaces."
