Sometimes it does happen. Do a bit of K9 and roll out and don't say much. I actually saw this one provider around my way two weeks ago. For some reason, she wasn't up to it. So, I didn't say anything to her trying to figure out what the situation was. I chuck it up as a lost. So, I just went in there, did my thing until I was tired, and immediately got dress, and rolled out. I didn't say good bye, make eye contact, or give any salutations.
