does it happen to you, too?

Does it happen to you, too that you apply maybe for 10 jobs and quite all 10 need a quick turnaround and need you to start right away, you apply and then... nothing, 9 of 10 clients that were in a rush, just disappeare. It´s not because they decline my application. Having a response, even if negative, would be good. The fact is that they don´t log in anymore. 9/10!? I can understand that some clients maybe don´t need that job done anymore or, maybe they find another solution, I guess. Does it happen to you, too or it´s just me that apply for job of "crazy (;))" clients?
