I like my steaks rare or medium rare. I don't mind if the steak is blue. I always ask for rare or blue, until I know the way the particular resto interprets the various terms for doneness.
I send stuff back, but I try to be polite about it. Do you have whole wheat bread? Is that real mayo, not salad dressing or Miracle Whip?
My ex used to get embarrassed about me sending stuff back. Then one day the server asked, "French fries or mashed?" I asked if it was real mashed or powdered. Ex-DH stared daggers at me and kicked me under the table. She replied, "Oh, they're from powder." Ex-DH very sheepishly asked for fries. He started sending stuff back that wasn't the way he had ordered it.
May you live as long as you wish and love as long as you live.
