No, they have housekeepers who do that. I once had Diana Ross on my plane, she had a *handler* sitting next to her to me she doesn't want any peanuts. I mean, she couldn't tell me herself, she had him tell me no peanuts. And he was even rude about it, he put his hand up and said *She doesn't want any!* I was like Who the heck is this guy? haha
I figure they do. People regardless of who they are need basic things like fruits, vegetables, nuts, basically food, which means even the president, needs groceries; it's just that he isn't the one who does that. The status might be different but the basics remain the same.
