The Delivery Dilemma
The local pizza joint delivered pizza and subs. Three employees were hired to deliver: John, Heather, and Luigi.
Based on the following statements:
- If John delivered pizza, then Heather delivered subs.
- If John delivered subs, then Luigi delivered pizza.
- If Heather delivered pizza, then Luigi delivered subs.
Which person or persons can we be sure always delivered the same food, and what food was it?
