Sounds like a regular called wanting to book more time on short notice.  It is very annoying when that happens.  I would not bother trying again if she is going to conduct herself that way.  Could also be something odd that made her thing you were LE.  I had a provider freak out on me once simply because my f-ing cellular phone started ringing while I was talking to her for her to buzz me through the apartment complex gate.  BFD  That is what a cellular phone is for, calls.  That is what cellular phones do, and they do that a lot.  This after I drove a long distance on a hot day.  I was not amused.  She did apologize later, but frankly that was not good enough after the bother I had gone through.
