Given that CSMs should have plenty experience of operating the MAN route, which is something like 40 minutes in the air, I can't really see what went wrong here, 17 in CE should be complicated. However what we don't know is if something else went wrong (e.g. oven failing, hot water flow, trays in the wrong place). I would write in to register a complaint. If you feel strongly about this you could think about a part refund of whatever you spent on CE, though that may take some effort.
