Using the walkie talkie feature has it's time and place. On the construction site, sure, I can see that. In the middle of the grocery store talking as loudly as you can because the sound isn't very clear and you have to ask them to repeat what they said over and over and over and not being witty enough to end the sentence with over everytime...horrible. If someone was walking around saying they have found the ketchup...over, then I'd laugh.
