You have a look

With the supply of the particular type of entertainment you envisaged clearly in abundance, you expected the demand to be relatively low, as anyone needing Asian girls to humiliate clearly could have their pick. You were quite wrong, it turned out; plenty of help is wanted, some (but far from all) at the very last minute. As with the offers, there is a very wide variety in the terms of what will happen, what will the pay be (if any), how long will it last and what preparation (again, if any) is required. A large proportion also makes it explicit that acts of sexual nature may be involved.

Some of the events would not have looked too far out of place even in your "normal" world; quite a few stag parties are looking for entertainers, for example. Most, however, would have made you raise your eyebrows if you were not getting used to this world at an alarming rate. The Rulebook likely has something to do with the latter. Wedding ceremonies (yes, the actual ceremonies, not any of the preceding fun) are certainly not the type of thing where you would expect humiliation to feature prominently, yet you see several adverts asking for exactly that. Plenty of house parties are looking for last-minute enhancements; organisations large and small are looking for entertainers willing to fit their specific needs. A teachers' union needs adult Asian school girls to be spanked by its members to let off steam. The city zoo wants girls for what you can only describe as petplay.

As you continue scrolling, you lose any doubt that you may have had that entertainment as a field is changed massively while all else seems relatively unaffected. You have to marvel at the Rulebook's power; your own position as a manager in charge of quite a few people coexisting with frequent humiliation is proof enough of it. Not only the change occurred; it also did so precisely as you intended it with no side effects that you can see.
