Yeah. that is weird. I've done my share of admin temp work while job hunting and a company large enough to take up two floors always had a dedicated mailroom with 1-2 employees. The most I had to do was, if I was covering the front desk, as to sign for FedEx or whatever. The mail guys would pick it up and make sure it got to the right person. It really sounds like they misrepresented the position.

And, wow, the president sounds like a piece of work, some sort of OCD/germ phobia going on there it seems. I am not sure what your state laws say, but when I worked those types of jobs, there were always 15 minute breaks. I would often be asked to cover for the recepcionist so she could go on her break, go to the bathroom, get a glass of water, etc.

That said, yeah, I think you are going to have to stick it out for the time being. It sucks, I know, but from what you say above you need to establish some more stable work history. As much as I have wanted to quit my soon to be former job, I had to do the same for months because leaving without severance pay would have been very bad financially. Big hugs! Hopefully you will be able to find something better in the near- to mid-term.
