Tiara (SL) First Soapland Experience With Sakura

You're not quite getting it. Only the bathing fee is listed on the site - the rest is highly variable.

People who regularly go to soaps understand this system - you can assume that the other fees will total 1 to 4 times the bathing fee (1-2 is most common, higher fees are usually for AV stars etc.). It varies quite a bit depending on the shop AND the lady - some ladies command a higher service fee than others, even within the same shop.

So if you see a bathing fee of 25,000, it will probably be 50-75,000 for a session there, but may go as high as 100-120,00 if the lady is famous.
Yes it’s a complicated system.
The standard fee is for using the shop facilities, the other fee is for the provider (which is usually higher than half so that’s nice) . Providers also pay a room rent per session and daily, but also get bonuses for repeat clients and so on, so if you’re popular the cost evens out well. This is because providers are not employed but “independent” in a sense.

But a lot of budget shops list the total fee on their sites and outside the building.

If it’s total it will clearly say “total”, if the fees are split it will say “bathing fee”.
