There's often more than one approach to solving any given problem, and many different possible skills that can be brought to bear on it. Some skills might have a better chance than others, while some might be relatively useless for various reasons under the circumstances. But it doesn't mean you should have only one possible path to success.

If your players want to try breaking out of a cell by dissolving the bars with orange juice and a car battery, rather than trying to lift the keys off the guard as you'd planned, let them go ahead.

And definitely give them bonus XP for having the presence of mind to bring orange juice and a car battery.

GM: You get a -2 divided attention penalty on each.
R2-D2: No problem.
GM: And you have to roll the dice simultaneously with two hands.
R2-D2: What? That's totally unfair! I'm gonna have to concentrate for this.
