4. You said final paperwork previously.

I'm not going to bother responding to the rest as it's clear there's some misremembering or exaggeration going on here.

In my experience, the things you are describing are very rare, and even more rarely intentional. Why they keep happening to you, idk.

Good catch, you're right. It happened with both a non-final sheet and the final one. The final one added in another line item that had not been agreed on.
