Commercial Kitchen

I have a mixed use office building with the potential for restaurant tenants on the ground floor. There is sufficient exterior glazing for tenants to easily meet this credit if they use open kitchens. However, counters separating the dining area from the kitchen area might exceed 42" above finish floor for the line of site. The reference guide states "Design teams may want to use alternate view heights for areas with nontypical functions." Since people in kitchen areas are typically standing while working and not sitting, can we use a standing height site line for people in those areas?
