me boss?

Today I had my worst workinglife experience ever. I had to give someone tha sack. That was scary. Thats basically it - except that I did quite well, I let her scream and swear at me and was still very polite and understanding and supportive (supporting her out of the shopdoors that is). The good thing was that my John (one of the volunteers who for a reason or other loves me dearly) said: if she touches you I shall beat her up, nobody touches my boss. That was cute. But i remained in my state of cool professionalism and said that no-one should beat anyone up in my shop, that wouldnt be in the interest of the charity (it doesnt say that in my assistants guidelines, but I made it sound as if, kind of: we as a registered charity do not agree with any kind of violence, not even in defence of an assistant manager in training.) All in all Ive decided that being boss is not my forte. Maybe I should become a famous painter. Do famous painters have a book thats called: famouse painters guidelines?
