As I understand it, the way Savage Worlds discourages players from doing too many things in a single turn is -2 penalties for each.  You can attack normally, you can attack and run at a -2 to each, you can attack and run and taunt at -4 to each, etc.  So technically you can do a bunch of stuff at once, but you'll be unlikely to succeed at any of it because you're rushing so much.

But what about non-roll actions, things that players can just *do*, like opening a door?  If a player wanted to run to a door, open it, close it behind them, lock it, flip over an adjacent card table, and then draw their weapon all in the same turn, how do I as GM handle that?  There aren't (as I understand it) any rolls necessary to open a door or flip over a card table that I could apply a -2 to, so how do I balance against people just loading up on those kinds of actions in a single turn?
