Move on.
Most of us that spent too much time in shops have seen this type of thing or had it happen to us. There is ALWAYS more happening than what you see at the surface.

Move on.

You will learn more from an environment that is not that one. I have never been afraid to walk away. In fact, I just did it two weeks ago. Myself and a few of my former co-workers have discussed this type of thing to no end. Most of them feel trapped and explain that there is a reason that they are supposed to be there. Now, much of that is likely due to the fact that they are supporting families, but they are not happy and they can not move ahead. I walked away. I know that it is time for me to leave a place when, at the end of the day, I know longer have the feeling that I am accomplishing something.

When I stsrt to hear ridiculous and irrational accusations I know that that feeling is soon to fade away.
