Person B did an unwise thing and spent the weekend working to fix the consequence.
If the problem was subtle and management didn't immediate corelate the action of Person B with the problem, they are likely to profusely praise Person B's working their asses off to save the company during the weekend.
On the flipside, if the company only contains A kind of people or if A people are too influential, it's likely that you'll stick in a local optimum where people are not incentivized to try out new things that may fail but may also succeed.
