ステーキが生焼け

Customer: Excuse me, I ordered medium steak. But it's still rare. Look at that.
Me: Ah really? Yeah, it's still rare.
Customer: Can you ask the chef to cook it a little bit more?
Me: Sure. I'll ask the chef to cook it more for you.
Customer: Yes, please.
Me: Sure. It'll probably take around ten minutes. Is that all right for you?
Customer: That's fine.

In the kitchen.

Me: The customer says this steak is under cooked. Can you cook it a little bit more?
Chef: Ahh really? (Checking the steak.)
Chef: ....ok, I'll fix that. It'll take around ten minutes.
Me: That's ok, thanks!

After ten minutes.

Chef: Food up! Recook!
Me: Thanks.

Me: Excuse me, here is your steak. Sorry about that.
Customer: Oh, thank you. No worries, it wasn't your fault.
Me: Thank you. Please enjoy your steak.
