I used to work in a call center in which we were instructed to make 50 calls an hour. Our pay depended on us fulfilling this quota. Most hours, this didn't prove to be a problem. At 7pm, there was a list of thousands of old grannies eager to be divested of their retirement fund. Things got trickier, however, on the night shift. At 3am, who do you call to fulfill your quota?
