We have one nearby (with the neon palm outside) who has been there for at least 40 years, and probably now a second generation. It’s a private home, and I gather that most people who go there just saw it from the road.
The gypsy I went to was in a small storefront with nothing to distinguish it. They would come into an area and rent a space, hand out their cards at shopping center parking lots, and wait for the calls.

I remember one outside Roswell NM back fifty five years ago. It took a while but the cops busted her when she tried to convince a client his money was cursed and had to be burned.
She took his money, put it in a sack, the palmed it and replaced it with fake money which she started to burn when busted.
A common fortune telling scam back then, probably still is today.
