They had no idea how to sell gold

I can^t understand why some people are angry at others who knock at their door and are trying to sell something. I don^t see anything wrong about it and I think that each and every one of us has to get money in some way and that is why we shouldn^t judge people doing this or that. It is all some kind of job thanks to which we can pay rent and keep on living. On the other hand there is no need to be rude, you can always be polite and state that you are not interested in their products. As a matter of fact I sometimes like to talk with people like that because they have an amazing ability to speak in beautiful way about the products that they are selling. Recently there were two men talking with me that wanted to sell gold to me. Let me tell you one thing. They couldn^t sell gold at all. I don^t know whether they have been trained or not (I assume they weren^t) but the company that has hired them should be ashamed of them. They were talking in wrong way with me and I think that with such attitude they will never sell gold. Still I was kind to them and I simply refused their offer. What do you think about it? Have you ever met similar people? I think that they will be fired anyway soon.
