Good job. But if you feel her comment is snide and a swipe at you, then it's okay to point that out.

"Oh I'm sorry, I'll remember foil when I put foods in the fridge from now on. Next time I'd appreciate it if you just stated your request. I feel insulted by the way you brought that to my attention." Then tell her you love her and ask her how her day was.
