Yep, pretty revealing and plenty of good advice. People that order meat well done, obviously have no taste anyway, so give them the crappiest piece of meat left and they won't be able to tell the difference as long as it's burnt.
Trouble is, with the e-coli scare, sometimes restaurants refuse to cook it any other way than well done. Personally I like mine medium rare to medium. I knew someone once who liked it barely cooked (stick a fork in it and it says "MOO"). I don't like it THAT rare.
Its far far from fine dining, Five Guys over grills its burgers (at least in one of its places here in Manassas). I just ask for it a little less burnt on the outside. When its that way, its jucier.
