While I agree...

...that no one may care what I had for lunch, there is a wonderful catering company located in our building, & they had extra today from a senior citizens Thanksgiving luncheon.

Is it rude go back for seconds on free food, even if you have to walk down three flights of stairs?
I mean, I'll probably totally work off those mashed potatoes on my way back down, right?
And then there's that nice dessert plate that I need to take back to them... . Maybe they've moved the other desserts to a carryout plate by now.

All of which begs the question, "Is it still ala mode if you put banana pudding on your peach pie?"
