Occupation change?

Today I filled in as a "hostess" at a local home builders office. I was told all I would need to do is greet and pass out facts sheets. Instead, I sold a house. I really didn't mean to, especially since I knew ahead of time that the copier wasn't working to that it would be near impossible to get the documents needed. Nevertheless, it happened and and I have 2 more people coming back in the morning. I thought I would be able to read all day.
Now if only I could get the commission on it.
