Yup, I don't remember the last time I went to mcdicks either. What I do remember was that I had stopped going after learning that (and this applies to most if not all fast food) it's "Generally Regarded As Safe", something I learned meant that if it was deemed safe to eat in the 1950's, while Drs would prescribe cigarettes for a sore throat, then it does not require any safety testing to add to foods.

The last time I ate there was a few years after when it was the closest option with minimal time; it left me feeling closer to feeling sick than feeling full.
