No, you cannot tell me how to do my job

With the thermometer hitting 65 degrees and my toes not seeing the light of day for 5 months, it was high time for a pedicure.  My roommate and I were sitting at the nail dryers when we spotted this woman whip out her iPad across the salon.  She proceeded to play a video for the nail technician on how to give a pedicure... while she was getting a pedicure.  After more careful eavesdropping we deduced that the woman was actually pitching some newfangled machine that performs pedicures for you.  She then asked if the technicians thought the salon owner would be interested in learning more about her product- you know, the one that could replace their jobs.  This woman couldn't sell a T-bone steak to a pack of hungry dogs, forget about pedicure robots.  Someone should take her iPad away.
