The coin fell and the
Machine burped into action, its belly
Rumbling, promising the delivery of
Instant overly salted, high
Cholesteroled delicious snacking
Something in its shiny face
Uncurled, and the bag of crisps leaned
Towards me almost dropping.
Almost
but not
quite
And I am left hungry
But perhaps the healthier for it
Perhaps the wiser
Without it

Truth, indeed! Great description at the beginning.
