I'm extremely impatient. After 5 minutes I'd presume that there was a fault with the line and hang up. Only to have to go through the routine over and over again as I become further behind in the queue. Then, to break the cycle, unless it was an emergency I'd give up on my mission and vow to try again later. By this point, I become far too frustrated and complain to OH until he becomes so bored of my ordeal that he deals with it himself (as it's usually a call he has asked me to do in the first place!)
I hate automated systems and being on hold
