Well, I refuse to eat in a restaurant which won't serve me a rare cheeseburger. Even if I don't want one at the moment I will always ask. If they say 'No' I then say 'Go'.
I'd love to pull in with a busload of people and do this to some idiotic restaurant some day. The management'll scream that it's the gubmint's fault, but they never protest until........
Why won't they serve you a rare burger?
