I hope you don't mean he told you that Walt dies. It's been said a hundred times that the writer wrote the series to begin when he gets diagnosed and end with his death. Even if you didn't know that, he had cancer, he killed people and he cooked meth. It was kinda obvious he'd die eventually.

You should have just left it there and walked away.

He probably thought you were being a loyal fan and re watching the series

You know, some people just have to do that! I can't count the times I've talked about going to a movie or reading a book without some idiot blurting out the ending! Happens to all of us!

I hope that cashier's head ends up on a tortoise.

should have attempted to burn the store with gasoline like pinkman.

Hey! Guess where you should never go again!

Dick move!

Throw the box in his face.

Oh yeah, I remember that ending! It was where Snape killed Dumbledore! No wait, wrong series...
