I haven't got all day
Can you tell me what this expression means.
It is a rude way to say "You are taking too long." It expresses impatience at the amount of time it is taking for something to be completed.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
