Public Use
While there is nothing preventing you from using all of the integrated objects in public and create truly scandalous scenes, there is a type of objects in DoS meant specifically for public or semi public space commerce.
Public Use Objects
There are currently these objects available.
Majestic Hole
Intended to be a more upscale version of the glory wall. Has several deco slots available to make it more thematic and a portrait slot up top which you can use for photos (medium size recommended).
Arcade Machine
For less exclusive look, you can utilize the arcade. Comes in eight varied swatches for that arcade cabinet look.
Blowjob Arcade
Focusing on oral service, the blowjob arcade has two handles to REALLY give it your all. Comes in a more anonymizing version with the side glass panels opaque, or the more exposing version that shows the occupant clearly.
Dual Purpose
The Contract Owner
While these objects are mainly intended for public use, you can still use them just like any other integrated object for the purposes of training.
As the contract owner, you can let any of your subs inside the machine just like you would for regular object training, however low skill subs have a much higher chance of providing bad service to the customer, discouraging them from further use and giving a debuff.
The Public
All other people who don't own the contract of the sim inside will use the public interactions. These cost money to use and provide a service buff / debuff conditionally. You don't have to do anything special, the operation mode picks the correct one automatically depending on the context.
To minimize performance impact, the machine advertises itself in about 15 units around itself, every 10 in-game minutes. So if you have trouble getting sims to use the machines, construct your public use space in a way where customers congregate near the machines.
Service Quality Setting
- Bargain - This makes the service easier to perform well, but pays the least. Good option for inexperienced subs.
- Regular - The default option, medium difficulty, medium reward. Full occupancy earns 600 simbucks per hour into the machine.
- VIP - Much better reward, but much harder to perform well. Only very good subs can provide excellent service consistently on this setting.
Service Outcomes
The likelihood of success is influenced by relevant traits- for example masochistic subs find it easier to provide quality service for masochistic interactions. By default public service interactions are considered humiliating and work with related systems.
- Bad Service - Removes any good service buff. Makes the customer angry and less likely to use more public services.
- Normal Service - Makes the customer happy for a while, makes them likely to continue using the public services.
- Good Service - Makes the customer happy for longer, making them even more likely to carry on using the public services.
- Excellent Service - Makes the customer very happy for a very long time, makes them ecstatic to keep using the public services.
Work Hard Play Hard
The machine occupant uses up energy when providing services. Should they run low, they will enter an exhausted state and the service quality drops rapidly.
The collected funds are stored on the machine and can be retrieved by any sim you control, using the provided interaction- Collect Earnings.
Paying The Bills
Voluntary Service
Sims you have control over, provided they are not certified Dominants or submissives can rent out the public use devices (simply place them on a public lot somewhere in the world). The voluntary service can be interrupted at any time by the player, but you will have to pay the rental fee again if you wish to re-enter the device.
Speaking of the device rental fee- it is a flat payment of 250 simbucks that goes into the lot owner's account.
Being used by other sims builds up passion for BDSM.
Employee Service
If you own a business the public device is a part of (as introduced in the Sims 4: Businesses & Hobbies expansion), you can instruct your employees to serve in the public device, even if they would normally not qualify to enter the devices.
Patronize Public Devices
New interaction category for your small business. Will make the public use interactions count towards the positive rating of your business, as long as you add it to the customer activities.
Customized Enjoyment
If your sim is handy with a wrench, you can apply several upgrades to the machines- Rejuvenating, Breeding Station and Milk Stimulation.
Made To Serve (the public)
For submissives serving in the machines, you might want to unlock the Public Servant development, which makes their service much more valuable.
