a brief departure

At the ice cream shop
we ordered
Rocky Road
to split between us;
though I just wanted vanilla

The cashier smiled
knowing she'd quit soon
and overcharged us
for a second spoon

I stepped outside
to take a call
and when I returned
found
my brief departure
led to a meltdown

You had left
sated,
escaped through
the back door
to the alley full of dumpsters
