Branch with if

decide --quiet prints nothing. Its exit code is the answer. The function asks_for_refund names what that code means, and if reads it directly.

The ticket asks for a refund. The if branch picks the refunds queue.

question="Does the customer ask for a refund?"
ticket=$(cat <<'EOF'
I renewed once this morning, but my card shows two charges.
Please refund the duplicate.

}

if asks_for_refund "$ticket"; then
  queue="refunds"
else
  queue="support"
fi

test "$queue" = "refunds"
