Who says it makes me "so upset." It's a minor nuisance that I describe as "annoying." But some people, like executives, big money clients, and just people with short fuses are set off by minor nuisances in ways normal down-to-earth people are not, and make their agitation known. The point of my post, as written, is that one ought not do this on their voicemail lest they perhaps end up ticking off someone they'll wish they hadn't ticked off. It's just a bit of advice, and genuine advice based on experience. Getting voicemail at all is frustrating, especially when a call is important. Why add to it? There's literally no logical reason whatsoever to do that.
