A Free Cookie

I didn't order it. I carefully chose foods
on my plan, what I could eat,
what would best serve my needs.
And you — the corporate you — 
knew better. And you added a cookie...
just a little one, a marketing technique
to sell the larger siblings. Or you added peppermint
or a sucker or something sugary. Without permission.
I've stopped you before, said to take it back,
that I didn't want it, and I'm not alone.
Others have done that but you don't learn.
Would you give away a cigarette?
A plug of tobacco, a pinch of snuff? 
A jigger of whiskey? Why not? What's the difference?
You warn about peanuts, wheat, other matter
I could be allergic to. But you don't consider
those of us who can't handle sugar,
who are addicted to it as much as a junky to pills.
Look around. Don't you see those of us
who would prefer to be healthy, to shed the pounds?
Would you please cease and desist the mandatory sweets?
