Getting blamed for something you had nothing to do with.

Here's the story. I work in an plastic injection molding factory. I run the finishing part where you stamp the color onto the parts.
Ask if you want more detail, OK?
I finished one job and got ready for the next.
I got the wrong color purple and the wrong color foil but didn't know it. The two head techs were there and so was the QC and they told me to run it.
2 1/2 hours later everybody and they're brother were jumping my ass because I was running what I was told to run.
I told them what for and they shut da f**k up.
I was ready for violence and I think they knew it.
I'll take the blame when I screw up. Not a problem. Oops.
But when YOU blame me because you're a dickhead...
I'm still PO'd at those idiots and it's 3 hours and a 6-pack later..
