The speaker obviously doesn’t want minute-by-minute updates. They’re joking about the situation.
Sarcastic TMU usage is common among close friends who understand each other’s humor.
However, because tone can be difficult to detect through text, excessive sarcasm may occasionally cause misunderstandings.
