I suspect the hate is coming from the person who paid for the very expensive cut of meat. As was mentioned early on, if you enjoy your steak well done, then you can pretty much get it anywhere and for cheap as there will be little to no difference in taste. So if someone is dropping big bucks on expensive meat, they might be a little miffed that they wasted their money. Granted, it's the money waster's fault for not checking before hand, but I can still understand why they wouldn't be upset at their bad decision.
I like my steaks "medium", but I still enjoy a little sauce on them - my unsophisticated palette just enjoys the flavor of the sauce, so it is what it is. Anyway, the reaction at the table when I asked for sauce for my very expensive steak was like I just told a mother that her baby was ugly. But it was similar to what folks are saying here, as the people at the table we advising me that I was ruining my steak.
