Nobody cares about a single or pair of car parks for bar staff. My
examples mentionned more significant features like hospitals,
factories or airports for instance with dedicated areas and service
roads for employees or visitors.
And we document access for deliveries or customers, why not for
employees or visitors ? Don't limit OSM tagging to your needs.
