at (one's) beck and call

Completely compliant or obedient to another person; catering to one's every need. The phrase has a negative connotation. Do you really think I'll do anything you say? I'm not at your beck and call! A: "How can we get to the mall this weekend?" B: "Oh, my sister will take us—she's been at my beck and call ever since I caught her sneaking in past curfew!" It would be nice to get my own work done without being interrupted all day long, but it's like the boss thinks I'm at his beck and call!
