Not what was ordered and meat was tough

Was embarrassed, at first, that my brother in law gave such a poor tip, however that was his way of complaining and fair enough. We ordered 2 of the exact same steaks but they brought us two different steaks. I don’t know if it was a mix-up of orders (probably not coz we ordered different sides and those were exactly correct) or a deliberate switch to offload an unwanted steak, but he accepted his incorrect steak and it turned out to be very tough (so maybe that one had previously been rejected?) My way of objecting is to never come back, because please explain why they would do that? It’s really simple when we ordered two of the same steak. How can you get that wrong? That can’t be a genuine mistake, it’s a deliberate trick to offload something.
