Stabbing someone in the chest, and THEN asking them to open a safe?!

I've learned over the years to obviously not take action movies too seriously, but the opening scene in Full Contact is completely unrealistic. They go to rob the safe at the store, the woman gets stabbed in the chest, and then they expect her to be able to open a safe?! Judge has to CARRY her to the chair. How about just threatening her by hurting someone else? I get that they wanted to open with a bang, but it just made no sense. Overall the movie was entertaining enough, but I just thought that could've been left out.
