It's not what you are doing but what you are perceived to be doing.
It would be interesting to see a Social Science experiment by dressing for the shoot. First dress down, with old clothes etc.. Second dress with suit and tie. Third put on a road workers jacket or a red flag safety gear like surveyors wear and a yellow hat. Fourth security guard coat and pants with an obvious badge hanging around the neck that says "Official Fine Arts Photographer" on it.
