Have You Ever Spent What Seemed Like an Eternity While On the Phone On-Hold?

Being put "on-hold" when you call someone on the telephone is one thing. However -- When you call (a business) and are put on-hold for more than five minutes, it is (of course) an annoyance, especially if you have things to do, and places to go; not to mention -- other places to call.

It's annoying, unless, you have nothing better to do, than to wait patiently listening to some cool elevator music, or to listen for the (repeated) recorded message that prompts you to wait, because all of the assistants are not available, and one should be with you shortly.

What is worse than being put on-hold, just to hear those recorded messages and elevator music? Could it be, playing phone tag, with the receptionist?

What are your thoughts about being put on-hold, when you call someone? And, have you ever spent what seemed like an eternity waiting on-hold for someone to get back with you?
