Soon after that my food arrived my an robot pulling a trolley with a food in it. The moment I lift the food, the robot automatically turned and went back from were it came, behind the glass door. I started enjoying my food. The marvelous rice felt delicious in my mouth. It is all the effect of hunger that cause the food to taste much better. While I was busy eating, something tapped on my shoulder. I turned around. My mouth agape by looking at the person standing behind me. I gulped the food and blinked to clear the vision. After having food, you feel sleepy. It probably the vision I am seeing. I turned forward as if I didn't saw anything and continued to dig on the food.
The person cleared his throat and tapped again. Ok, I'm not imagining things. I can hear the voice now. I looked through my shoulder, it was the same person that was there half a minute ago.
