....Restaurants that charge an arm and a leg and insist on you eating the way they want to eat? They don't get my custom. Simple.
I'm Ok if the chef recommends how they think it would be best enjoyed but if they flat out refuse to cook it how you want it then its time to eat elsewhere. Sounds like the chef in your example took a very pragmatic view and was willing to accommodate but wanted to make sure everyone at the table understood what it would take. Kudos to them.
