All day

'All day,' as in "taking all day," or "I don't have all day" is a way to complain when you think something is taking too much time. It is usually said when the person being complained about is not within earshot, by a person who has power in a situation, or among close friends in informal situations.

Examples:

(To a friend while the salesperson in a store has stepped away) -What's taking all day?! It's just a simple return!

(To employees) -Come on, people! We don't have all day!

(To friends) -Come on, you guys! Let's go! I don't have all day!
