Part of my job is taking calls from the public. I can hear everything going on in the background and I wish people didn’t think phones were a magic device that only picked up speach. I can hear you eating, peeing, breathing. I can hear Wheel of Fortune in the background. I can hear the baby screaming on your lap. If you put me on speaker phone I do hear an echo of everything I say.

If you call someone be courteous and do it from a quiet place.
