I generally have little patience for the haters who want to blame America's collective and individual giant fat asses on fast food in general and Mickie D's in particular.
But...I have to admit the anti-oatmeal bitching is pretty much on target.
Tried it myself:
1. Asked for no cream and no sugar. Got both.
2. Took it back. Was assured that could be done. Got both again.
3. Took it back. Manager came over. No, turns out can't be done. Can redo without sugar if I really WANT to, but cream is already mixed.
4. I just left it on the counter, and left.
McDonalds insists you can customize, but it's actually not true.
