How do you brand a group of venues?
The group shares the mark and the usage sheet, and each venue adds the neighbourhood or the trade if the menu is not the same. It does not work as a different logo on each manager's whim, nor as a clone that ignores one being a clinic and another a shop. List what is the same everywhere (name, manner, colour) and what changes (address, hours, speciality). That list is the system. Each Madrid site orders its own sign and the group stops being recognisable on Google. The customer at the second site thinks it is not the same house.
A group master and one board per venue with the address and what is allowed to change. The shared folder stops the third site from redrawing the mark.
