No Second Chances

Customers are unforgiving. If you make a mistake, that's it. You don't get to start over. If you begin the call by addressing a problem they don't have, if you accidentally call them the wrong sex, if you accidentally say their name wrong, or can't figure out what their e-mail address is because they (The_Mumbler) mumble, they immediately demand that they "talk to someone else."

Example:
 * One customer was especially unforgiving. She asked to know the amount of time you were allowed to ask for a price adjustment on a Valentino shoe, but the way she phrased it made it sound like she wanted to know how long our 65% off sale was.  Seriously, I thought she was wanting to know how long the 65% off sale would be going on so she could place an order for the Valentino shoes.  Before I could ask what she meant, she asked to speak to a supervisor.  Thankfully, nobody was on the escalation line so I could tell her that nobody was available to help her except me.
