at one's beck and call

Required to tend to someone’s wishes; totally under someone’s control. The obsolete noun beck, which survives only in this cliché, meant a mute signal or gesture of command, such as a nod of the head or a pointing of the finger; the verbal form, to beckon, still exists, as does call, for a vocal summons.See also: and, beck, call
