Cleaning Products on a Cold Night

This girl was working late...well not too late by the clock but it was dark and cold.  She rang the doorbell and then stepped way back.  When I answered the door she stepped forward and handed me her flyer.  It was for a product to clean the hard water stains off our shower walls.  When I told her I wasn't interested I handed back the flyer and turned to go into the house, she didn't immediately take it and I almost dropped it.  Door opening to closing, 19 seconds.
