Answer: Win, because Bob is still liable to Al.
Step-by-step explanation:
Accepting to do a job must come with commitment on the side of the servicer. It is unjust to accept a job without making much effort or input to see it carried out. Some businesses do this especially when a bigger offer comes their way and these puts a bad name to their organization as the failed client will have no good thing to say about them, when the cases goes like this, the client who was failed raises the issue to court and would win since he has already engaged the services, this is the tail between Bob and Al.
