What Happened to McDonald's?

This morning I went to the local McDonalds (which by the way is the ONLY fast food restaurant here) to get a quick breakfast for my daughter and me after she went to the orthodondist. This particular McDonalds is crappy to be sure, but the breakfast sandwich I got was about the worst thing I've ever tasted. I have always been able to eat McDonald's food. I know its bad for you, but sometimes it's the only choice--especially where we live. Anyway, the bacon, egg and cheese on a bagel was horrendous! Some neon yellow goo oozed out when I took a bite. It certainly was not butter either! It tasted like ranch dressing mixed with some sort of fancy mustard. It was awful and really not something I would imagine anyone would want for breakfast. What in the world has happened? Are all the McDonald's breakfast sandwiches slathered with that crap or is it just that this particular McDonald's is having some sort of crazy breakdown with their sandwich making? I was so upset that I wrote to the McDonald's Corporation to complain. What a waste of my money! I'll never order that again!
