This thread amazes me. I have used the free internet access at McDonald's in France but I have not been brave enough to order any food because the greasy smells were quite enough. I last ate in a McDonalds in San Francisco in 1981 when I was flat broke and it was the cheapest place in the area. I've had no desire to be in one since.
I've noticed beer being served there, and ordered one because the internet should cost something, but I could not even smell the beer because the greasy odors overwhelmed me. I tasted it and thew it out. It tasted like dirty water.
