/**
 * Admin failed order email (plain text)
 *
 * This template can be overridden by copying it to yourtheme/woocommerce/emails/plain/admin-failed-order.php
 *
 * HOWEVER, on occasion WooCommerce will need to update template files and you
 * (the theme developer) will need to copy the new files to your theme to
 * maintain compatibility. We try to do this as little as possible, but it does
 * happen. When this occurs the version of the template file will be bumped and
 * the readme will list any important changes.
