Biting the bullet butter

"Have you got any butter?" I asked the barista at the Slow XS Lounge in Lanseria. He had just passed me a double espresso. "Sure," he said, and passed me a couple of single serve tubs. He then watched in fascination as I tipped both into the espresso.

"I bet you've never seen this before," I said. He shook his head slowly.

"Is that Bullet Coffee?" asked the woman in line behind me. "Sort of a poor man's version," I said.

"Why?" asked the barista.

"It stops you getting hungry," said the woman. "Exactly," said I.
