My God, all this talk about food is laughable. If you need to eat, eat! Do some coordination, plan ahead I you can. But god if it's been 6, 8, or longer hours since you've had food go get some. Tell the gate we're not boarding until we get back then we need 10 minutes to inhale or even 15. Push late who cares. I've explained this to the pax and the CPO, never had an issue. In fact the cp said good lookin out for your crew.
