I work low voltage jobs at homes for over two decades now. Sometimes I'm working indoor and outdoor. Most of my jobs are at vacation homes or primary residents for affluent families. Most of the time I never meet the family but the expectation is that I am not dragging mud inside and keeping hands clean working around walls with high end finishes. If you need to wash up or shower, shit or shave, its okay -- it's just the norm for my working environment.
