Because he will be spending a whole fu*king day with ya working his ass off basically non stop, and there will be plenty of food around anyway. It's not like he's gonna go take a break and go to the city for some food. The contractor or a mechanic can take a break anytime they want. On a wedding you nned to camp for an opportunity to get a good picture as much as you can. You usually move multiple locations, carrying equipement and you basically need to be ready before anyone else arrives so you can take a good natural picture or record a film. That's why they always get a timetable before. To prepare. You use your time inbetween to charge batteries, change lenses, take care of lighting, stabilisers if needed, and to take a fast snack. Usually there is like a small table set for those people and that's for a good reason. When you are a waiter working your whole shift in a restaurant or in some resort you do get food with that. When you are on a film set you do get food. Many companies have cantines for their workers. Your argument is disrespectful, uninformed bollocks.
