NC V4: Thermal Comfort

Hello, I am working on trying to obtain the indoor environmental quality-thermal comfort credit for a new construction. To be specific, the new construction is a restaurant. The credit states to provide individual thermal comfort controls for at least 50% of individual occupant spaces and that the thermal comfort controls shall allow occupants to adjust at least one of the following in their local environment: air temperature, radiant temperature, air speed & humidity. So what I'm wondering is if it's for a restaurant, do customers dining need to have this control at the booths, tables, etc? or is it enough for the workers to adjust one of the following stated above in order to obtain the credit? Your feedback is greatly appreciated. Erik G.
