Cellphone etiquette

This has absolutely nothing to do with wholesale, marketing or even the internet, but I feel that it must be said: When you end up playing phone-tag with someone (namely, me) and you are merely returning a missed call, don’t leave a voicemail saying that you’re calling me back. I already know that you’re calling me back from the little message on my phone that says “1 missed call.” Not only is it ridiculous and redundant to leave such voicemails, it’s a waste of my anytime minutes, not to mention my precious time. I know I can’t possibly be alone on this one. It’s like walking into a public restroom and announcing your intention to tinkle. It’s asinine! Don’t do it! Thank you.
