Record time

We had a temp come in today for her first day to do some office work for us and basically help keep us on top of stuff. I walked her through our database and some of the things we do here, showed her how to do a few things, taught her the phone system, etc. This took maybe an hour. I then gave her some things to do such as a couple phone calls to make, some things to look up online, etc., told her to do as much as she could today and let me know if she had any questions at all or needed any help, and then went back to my desk. Five minutes later, she said she was going to take an early lunch, walked out, and never came back.

Am I seriously that off-putting?
