So I have had this handled in a number of ways when I've been served steak, as I said. One time, they brought out the steak, and it was a bit rarer than medium, and the wife said, "Oh no, that's not cooked through yet" and told her husband to put it back on the grill. One of the men there said, "It looks perfect to me - can you please keep one off the grill for me?" The wife said that wouldn't be possible, they weren't done yet, and they put them all back on the grill. They seemed even beyond well done to me, but the wife talked about how perfect they were and said something like, "Everybody congratulate (huband) for how well he cooked the steaks!" And then to him, "They're really perfect." I just stayed silent and felt uncomfortable. The guy who had asked for one to be kept off looked angry. I don't know if I'd get angry but it was a buzz kill anyway.
But then I can imagine others might have been served steak more to my liking and felt equally off. I've been to dinners where they've all been to me perfect, every single steak. I have to guess someone there felt they were all underdone and was equally uncomfortable.
I guess I'd want to ask each person how they like them, or at least serve them cooked to a variety of degrees.
But like I said, I've really just kept away from steak.
