Sharing charge at restaurant for $60 entree.

Edit 1/24/25: the manager finally called and apologized and is sending me a gift card so we can return and enjoy a more positive experience. He also will be revisiting their policy about a sharing fee for upper priced items. Thanks for your input!!

We went out to dinner last night and they had a 40 ounce steak on the menu for $60. That certainly is big enough to share so we ordered that. The waitress came back and said there's a $20 sharing charge and we would be better off ordering two separate entrées. I could see if we were trying to split a $25 meal but what the hell?! It's was $60 and two different entrees were $56. Plus we got a $20 appetizer, dessert and wine. EDIT to add we wound up NOT ordering the steak out of principle. We ordered the two entrees coming to $56.

We have ordered this before and have not had a sharing charge and when they do serve it, they serve it on one big platter so it's not like the chef has to take the time to divide the plate up. It's always been up to us to divide the platter. Should I write a note to the owner or just shut up and stop being frugal?
