Is that any way to talk to the person who's letting you live in his house?

[Still, this is the reaction he expected, so it's fine.]

I ended up staying late at work, and since I was already late anyway, I thought I'd buy you something you could eat as soon as I got home, so you didn't have to wait any longer. Or should I just eat these shrimp myself?

[He wouldn't do that, though.

Probably.]
