The phone is the single most powerful device on the planet right now. It can stop nearly all conversations in their track.
I've had people walk in my office, interrupt my work, then ask me to wait while they answer their phone. If I'm in a meeting with someone and they answer the phone, I do the polite thing, I walk out. ;)
Someone told me once to never take a phone call when talking to someone. The person in front of you should feel like the most important person in the world.
To this day, if someone's in my office I will let the call go to voicemail. If I'm expecting an urgent call I will apologize before picking up the phone.
I've worked in locations where customers talk on the smart phone while being served. It's just plain rude. Ironically, most of these people were coming in to tell us they needed more time to pay their utility bills.
