I was watching a drama and in the scene, the coach was speaking to her team:
Coach: 希望每个队员都能拿出最好的状态。能不能做到 (I know all of you can do your best。 Can you do that?)
Coach: 都没吃饭吗 (Not loud enough!)
Can someone please explain to me why "都没吃饭吗" can mean this? Would you ever use that to ask if your friends have eaten? Thank you!!
