When you call a place like Five Guys or Pizza Hut or anywhere that is a business that accepts calls from customers, when they say "can you please hold?" is it actually a rhetorical question? or better yet, is it actually a demand posed as a polite question...which is just "polite" for "I have something else to do right now so I can't talk to you, so HOLD! If you don't like it, TOUGH!! At least we 'asked'?"
Because think about it, when the voice on the other end of the phone asked me if I would please hold...what were my options? I could have said, "No! I won't hold! " but where would that have gotten me? Would she have actually stopped ringing up people in my ear and heard my question? I highly doubt it! So I just said "sure!" and held the phone until I figured she was never coming back to her end--she was taking orders and talking to co-workers--and I hung up! (I called back about 10 minutes later! I got put on hold again! But this time, the chickadee came back to the phone!)
