A footy fan has had his bad day go even worse when he bit into his meat pie, to discover.. it has nothing inside.

The Adelaide Crows fan was in the middle of watching his team lose against the West Coast Eagles at Adelaide Oval on Saturday when he took a bite into his pie to find the meat was missing.

The man who is anonymous, posted a photo to Facebook, saying “Hey Balfours … forget something?”

Some made jokes that it was the bakery’s new “the new weight watchers range” of savoury pastries.
