He was right. They just cook a new steak & more sauce can be put on that one.
The problem with sending it back it that unless you immediately flag down the waiter which is almost impossible to do, then your poor son would be sitting there with nothing to eat while the rest of the family was enjoying their meal.

There is no good solution. Al least at home you can keep the other steaks warm while getting the one more well done.

I ordered Duck ala'orange at a really fancy reztaurant for my birthday one time. The duck was burnt black & dry. I couldnt eat it. I was waiting for the waiter to even show up..you know when they ask is everything ok??? He never showed his face until everyone else was done eating their meal. I ended up complaining to the manager but got no results. Needless to say that waiter got NO TIP & i never went back to that restaurant again.

Had another steak place where my steak was too done also. I like mine almost mooing. They not only brought me another steK but gave me 2 free meals for in the future at that restaurant. You can bet I went back more than just for the free meal.

Other kind of customer service from Lowe's for the really expensive refrig I bought though it was on a huge sale, the french doors werent closing right. 2 times the installers came out to fix but didnt & couldnt. I was supposed to hear back about what they were going to do & NOTHING. I called the store & they made an appointment for the appliance manager & his assistant to come to my house in the country to fix it. They called as they were leaving the store to let me know they were on their way. I gave them better directions. They arrived ON TIME, they started adjusting the door & got it better....the manager said....we are here, we are going to make this door PERFECT & that is exactly what they did. Love my new expensive refrig & the perfect closing door & how consciensious the manager & his assistant were in getting it fixed. He kept apologizing about the unconvinience they put me through to get it right. My patience without getting angry though staying persistant, got me the service I wanted.
