I imagine the crew have seen a fair few beef cheeks over the years and get sick of them. 😝 Seriously, though, they’re at work, many crew might appreciate a meal but many more will, I’m sure, bring their own. After all, if you’re trying to eat a controlled diet, and keep healthy (an occupational requirement & easier said than done) you probably need to be quite self disciplined. These people work shifts at all hours, travel through multiple timezones, are subjected to pressurisation / depressurisation, and locked in a thin metal tube with hundreds of members of the public…I doubt scoffing the chicken massaman curry is their top priority, especially if this is going to lead to a potential complaint.
Surely happy passengers = happy crew so getting through flight with minimal drama must be key. If anything you’d be more likely to give up ‘your’ meal just to make the ‘gentleman in 4A’ shut up.
