What is the first name of the person that the hooker steal a car from?  Answer the above question based on the context below:  Dave Walsh is a bank employee whose day begins badly when he gets fired from his dream job and dumped by his fiancée Sara Goodwin the day after their engagement party was crashed by his best friend, Jack. Jack tries to console him by telling him that it's for the best, that Dave was headed down the wrong path. In a further effort to console him, Jack arranges for a hooker named Whisper to show up at his apartment, but instead she steals his car. The next day, Dave goes back to the bank with a gun tucked into in his waistband. He surreptitiously makes his way into his former boss's office, where he pulls out the gun and threatens to end his boss's life. Though intimidated, the boss stands up to Dave, and Dave, deciding he does not want blood on his hands after all, pistol-whips him instead.  When Dave emerges from his boss's office, he finds the bank being robbed. A sequence shows him killing the robbers single-handedly, but this is then shown to have been a daydream. When one of the robbers seizes his co-worker Wendy, he shoots the robber and saves her, but he is shot, tackled, and forced into the getaway vehicle, whereupon the robbers make their escape.
The answer to this question is:
Dave
