I find it the rudest thing and disable it immediately on my phones.  It screams "you're not important to me; let me see if there is someone I'd rather speak with" !

I don't use call waiting but I know others who do.

I don;t typically use this feature when it comes to business and even most of the time with personal calls. I want each person to feel special and uninterrupted. 

Only once in a while, and i do find it annoying.  If the call I've been waiting for for the last 30 years comes in, I may take it.  I really don't want to interrupt a conversation with a client.

I have call waiting, but I don't always take the call.  If I'm catting with my mom or daughter and I get a client call I'll take it. But I would never interupt a business call for another. I just get back to them.

I don't use it.

I have a girlfriend that has call waiting on her home phone and cell phone and almost always wants to take that call. I finish my call and then call the person cutting in back.

sometimes.

It is a feature that comes with our cell phone service.  I will not end a call to take one BUT if it is a friend and another call comes in, I take it.  Or if we are near the end, I rush off to accept the call waiting.

I use it and it all depends on what the conversation is about, who I'm speaking with etc.

One thing is for sure, the person who I am speaking with gets priority so if I do answer the other call it is a maximum 5 second phonecall. If it happens again during the same call I usually don't answer it.

I would never put someone on hold to answer another call.  So yes I wind it annoying.

I turn it off. I despise call waiting. I find it rude. If I see someone calling while I'm on the phone I'll quickly text them that I'll call back shortly.

 Good Monday morning Capt. Wayne. No, I do not use call waiting.  I do my best to answer the phone by the third ring.

I don't use it often but if I am talking to my kids - which are all grown - I might if a client is calling.  Really depends on what might be going on with the client.

I don't as I don't know how to use it. Plus, I am too impatient.

I do have call waiting on my cell, and actually can get three calls at one time.   Who could answer three?

Sometimes I do but often am not quik enough to catch the call.

I find it annoying. Occasionally, it it's a hard to reach doctor, agent, or client, I will take it...
