Read a thing once that said to ask what "other tasks" usually look like before you sign, so it's on record. Hard to undo now, but maybe ask for a written list of what you're actually expected to do going forward.

This is the same thing that happens with cooking meat, nobody tells you to let the steak rest before cutting it and then you wonder why all the juice runs out. It's like there's this whole set of unwritten rules that everybody just knows somehow and if you didn't grow up with it you're screwed. My theory is people learned these tricks from a grandma or a mom standing next to them in the kitchen and it never got written down anywhere. Meanwhile the rest of us are out here following the bag and wondering why our food looks like a science fair flop.

500 dinners?? That's insane, I can't even imagine.
