Free refills

Slurping like a terrible water demon the boy consumed his beverage.
The last dying moments of a soda fountain refreshment
Shrill and unforgiving.
Then,
crunching like a wild animals do on leftover bone,
gnaws his popcorn down to the hard unpopped kernals,
which are then chewed on relentlessly.
meanwhile,
everyone else in the theater are annoyed by his racket,
for a good show can be ruined by the slightest interruption.
with intruding cacophony at a pristine moment - all is for nothing.
unexpectedly,
the boy rises to a height only shadows can achieve,
the empty troffs in hand,
and leaves the scene of his offense.
with this,
some viewers rejoice,
think their torment is over,
the wiser in the audience however know about free refills.
