Sales people can be some of the most annoying people in the world. Some of the traits i find to be extremelly annoying is how they never say no. Door salesmen will just keep talking and talking and won't ever stop and when you say you don't want something they keep talking anyway. The same is basically true with all other types of sales people for instance telemarketers call and call and just annoy you by there repetivness and taking time out of my day. These telemarketers do need alot of backbone though. They get rejected and yelled at for a lot of reasons. It is tough being in that job and you have to give them alot of credit it is extremelly hard to have people yelling at you. Although they can be annoying there just trying to earn a living also, i just hate the companies that hire the telemarketers to call.
