The Golden Elixir

When the man entered the Golden Elixir, he was the only patron. The name was for both the establishment and the only drink it served.

The bartender greeted him in a friendly manner. "How'd you hear about us?"

The man wasn't sure what to answer. "I heard rumors that you serve drinks that are...solid gold?"

"That's true. Would you like to try?"

"Sure, how much?"

"The first one is on the house." The bartender pulled down a black decanter filled with a gold liquid and poured a glass. The man hesitated, then gulped it down.

The man immediately died.
