Entering and leaving, paying up at the reception desk, walking to the room, going to the toilet, etc.
It's the same with any brothel. Being seen by other customers is almost a given. If you are so concerned about this, you should stick to privates (use good agencies instead of bait and switch cheapass ones!).
On a side note, not a brothel but close enough. I find that Linda the mamasan at CBD Style Massage goes out of her way to ensure that her customers never see each other. She does this by default. I personally don't give a shit about being seen, and find it amusing (sometimes annoying!) when she does this. From memory, she's the only current shop keeper that does this.
