The Ad Infinitum Call-Waiting Technique

If you are told that your target contact is on the phone, simply reply,

"Oh, that's fine. Will you please put me through as soon as that call is completed?"

If the Guardian of the Gate says it may be a while or that she already has other calls waiting, reply,

"Oh, that's okay—I don't mind holding. I'll be working on some papers while I'm on hold."
