Paranormal: Debunk your personal experiences

I’ve told this story before.
Paranormal experience:

Many years ago shopping at the Waldbaums in NY, late in the day near closing time the store was pretty deserted. Walking down one of the aisles I suddenly heard a voice say “Buy one pound of roast beef or ham at the deli counter and you will receive one pound of potato salad or macaroni salad for free”. I looked around but didn’t see anyone around who could be speaking so I continued shopping. Then in the next aisle I heard the same voice again telling me the same thing. It was certainly quite eerie, but I figured it was some kind hunger induced hallucination. However, I did want to pick up some sliced roast beef at the deli counter so I stopped by there and ordered a pound, saying nothing else. The guy sliced the meat and handed me the package, and then out of nowhere he said “You can have a pound of potato salad or macaroni salad for free”. Somewhat stunned I took the macaroni salad.

Debunking:

Well I can’t really. It was either a hunger induced hallucination or I heard the voice of God. There’s no other explanation I can think of.
