There is parking close by like duggi mentioned, but I personally park at the Stockton garage. I make my appointments in the morning, make sure to be aware of my surroundings and social distance and ask for a white shopping bag.
Also, because I usually have the first appointment of the day and drive from South Bay, I tend to look like utter trash because I'm rushing to leave the house before 9am.
Though I do intend to actually try to wear some H for my next appointment not going in there full vagrant style.
