There were walls, but no door.

But I remember going to 208 oasis massage in parramatta rd early in the morning at like 10 am through the back door. This was just after covid and only a gilf (maybe mamasan) was working there. Gave me a hell of a massage and a rushed HJ. Only problem was the door was wide open and I had a good view of the washing machine and garden at the back. Also, it was the start of the morning shift so a couple of MLs walked through the back, laughing (presumably at me) while they were going to change clothes.
