One time at my old job, a lady came into the store with her husband and kid (who was probably 9 or 10). She really didn't look like she wanted to be there, and the husband was taking way too much time.
So, to make an excuse to leave, she pretended that her son really needed to go to the bathroom. When I wouldn't let them use the employee washroom (the public one was just down the stairs), she started throwing a nasty fit, cursing at me a whole lot and insisting that her family would never be coming back, the mall manager would be hearing about this, blah blah blah. Which was enough to let the poor guy be dragged out of the store.
She spent more time bitching at me than it would have taken her to walk to the bathroom, but I guess that wasn't the point...
