Why didn't they just pay Tanen?
I'm sure I'm not the only one who's thought of this.
I really love these movies, and I know it wouldn't have been heroic at all, but at the dance, if I were Doc, right then and there I would have told Tannen, alright, you win, I'll pay you, how much do you want, will you PLEASE just spare my life.
Yeah, kind of cowardly but when it's you friggin life on the line, and they are already putting so much bother into trying to get back to the future because of it, you'd think he would have at least tried that. I'm sure Tannen might have still just been like, no, I'm just going to kill you, but honestly, given his character, if Doc actually took it upon himself to humble like hell in front of him, it would probably please him enough to say, "Make it a hundred dollars! Tommorrow! No pay, you get the bullet boy!"
I know it would be lame, but if we're being honest, I think we'd all offer some dough to save our skin.
