If it weren't for the ignorant in our society, you wouldn't require privacy, but if you feel you need it, you certainly deserve to get it.  Our relatively small, 3 story building in quiet Marina Del Rey has 2 lobbies.  As you enter the South lobby our office door is right in front of you & there is only one other office on the ground floor with little or no traffic, so access is very private & no one is likely to bother you, especially in L.A. where people mind their own business.   They just don't care as long as you do your job.
