Rude to ask for a big meal at interview?

<p>I got my interview kinda late at night, and I have a chess competition right before it so I have to go there right after. Since I don’t have time to eat dinner, I kinda want to ask my interviewer to get me a big meal. I want to pay, but I can’t because he already insisted buying stuff for me, but I don’t want to be rude, and I’m really out-of-it when I’m hungry…
So… What do I do!!!</p>

<p>Pack a sandwich to eat between the chess competition and the interview.</p>
