If you ordered food but it was made wrong how would you handle it?

I always say something

I'd take it back and politely complain to the manager on shift.

But ....is it still delicious?

I only speak up if it's something big, like recently I ordered a burger cooked Medium. But it came medium rare. I don't mind some pink but it was almost red in some spots. I did speak up on that..
Often times if it's the opposite and the meat is overdone , I just deal with it. I'm afraid they'll spit in it😧😩

Made wrong is not very clear. Have I hit a restaurant or am I getting carry out? If I'm in a restaurant and I order a steak and it's still walking, yeah, I'm gonna speak up real quick.

If I'm leaving McDonald's and I see my Big Mac has been replaced with a quarter pounder with cheese deluxe? I'm driving away. I got the better part of the deal this time.

Not drinking or paying for milk in my coffee...sacrilege has taken place.

If my steak is over cooked it goes back. I do warn them as I order.

Depends - people are human and they make mistakes, read an order wrong, etc. So, if it is wrong in a way that makes it unfit to eat, I say something. Otherwise I chalk it up to humans being human.
