The solution to such widespread idiocy, incomprehension of responsibility/duty, and lack of teamwork is simple: Just like in a freighter, before pushback, go right into the galley yourself and stick your meal in the oven for 25 mins, and go get your own meal at TOC along with whatever else you want, whether the SP (or ISM) likes it or not. When they threaten to "report" your behaviour, invite them to send it right to the head of corporate safety, where it will be right along side your report about the cabin crew causing pilot discomfort, distraction and frustration that interfered with the normal operation of the a/c.
You can also take a moment to remind them who is in charge of them, the pax and the a/c, too. If we stopped accepting such disrespect and arrogance from the unskilled labourers (duh: seat belt enforcers/food and drink servers/potential door openers) things like this would stop happening.
