Hi, I had one of those moments today. I work in a cubicle environment (Dilbertville) and my space is right near a conference room. Folks entering and leaving tend to be fairly loud, so I usually just keep my earbuds in most of the day.
Today, I was working on a presentation, going back and forth to the central printer that's about 100 feet away from my space. I had my buds in and my iPhone in my pocket. Anyway, I passed co-workers and gave the usual greetings.
What's the bud etiquette here? One bud out? Both buds? Obviously, I'd remove both and turn off the iPhone if I was in a deep conversation, but what about those casual things or when people stop by your cube to ask one question or fill me in on one fact?
