Good-Person
Captain Junkie
I really don't know why people would decline a sales representative job. I guess you have not just found the right person. Many people are out there looking for jobs and I am sure would be so interested in this, or at least here in my country that is how it is.
Many people would refuse because they simply might not be interested. This is why they tend to pursue a career they like the most. Not all of them dislike such kind of jobs.
