A man walks into a bar and sits at the counter. He asks, “What’s the WiFi password?”. The bartender replies, “You must buy a drink first.”
The man says, “Okay, Can I get a Coke?”. The bartender says, “Sure. That will be 3$”
Once he gets his drink, the man asks again, “What’s the WiFi password?” The reply comes, “You must buy a drink first, no spaces, no capitals”
