Well, some us work in careers that have tight circles (read: a few major companies to work for). Pissing off 1 out of 3/4 possible hiring companies can be far reaching into your future prospects.

I passed on a job offer I got from a company that really seemed to want me. At the time, I was interviewing for another job I was interested in and had a really good feeling about it. I didn’t want to be one of those people who took a job and quit a week later.
