You can never underestimate the entrepreneurial spirit of Texans!
We have a small casual office and go barefoot in the summer (and early spring). When we moved in we decided to leave the door locked during the day because we don't like being interrupted by random stoppers-by.
Well, today a guy came by as I was walking barefoot past the glass doors. I answered his knock and he asked "shine your boots?" I lifted my bare-foot and he replied "we shine feet too."
Now that is a true entrepreneur!
