Good news if you are in or near LA.
I recently visited a flower in a high-rise apartment complex on Wilshire a mile or two west of downtown. For those not local this means that traffic is busy but moves easily & that parking is plentiful. When you park they give you a five-character code #nnnn which lets you in the front door & tell you the floor & room number. I went through SA to make the appointment.
Inside you likely will see a building guard. You can ignore him or just nod or make some neutral comment. I think they are just there to keep an eye on things. Go to the elevator & up to your appt.
The lady who opened the door was Asian & was gorgeous by my standards. She was friendly & experienced. I had a good time.
I live in Hollywood 20 minutes away during most afternoons. I'll be back.
