Take your time*

Used to express your displeasure with someone who makes you wait.

Mr. and Mrs. Karen are in a store. The only visible employee is busy with some boxes laying around on the floor. He notices the customers but turns away from them and continues sorting the boxes. The couple hovers over him for a few minutes and then Mrs. Karen says acidly, “Take you time, young man. We’ll just stand here and wait.”

*Some common phrases may be used in a sarcastic way. It’s usually the context (or/and intonation) that gives away what the speaker actually means. Sarcastic words are not to be interpreted literally; they convey the opposite meaning of what seems to be said.
