They might be about difficult clients. For example, some clients could be very demanding, asking the princesses to do things not in their normal routine, like staying extra hours without proper pay.
Perhaps they've had bad experiences with co - workers or managers. There could be competition among the princesses that turns nasty, or managers who don't support them properly. Like one princess stealing another's costume or a manager booking too many parties in a day so the princesses are overworked.
One horror could be dealing with unruly children. Some kids might be overly excited and end up pulling the princess's hair or costume.
In a DND party I was in, we had a cleric who was not very experienced. We were in a dark forest and he tried to use a powerful healing spell to revive a fallen comrade. But he misread the spell and instead of healing, it summoned an evil spirit. The spirit started to drain the life force of all of us. We were so scared and confused. We tried to fight it, but our attacks seemed to have little effect. Eventually, we had to flee, leaving behind some of our precious items in the process.

Well, in a bachelorette party I attended, we hired a party planner. The planner completely botched the whole event. She got the wrong decorations, the music was terrible, and she even invited some extra people who were not on the guest list. It was chaos. There were arguments among the guests because of the overcrowding, and the bride was so disappointed. It was supposed to be a special celebration, but it turned into a nightmare.
One horror story is when a girl planned a surprise party for her friend at a rented hall. But she didn't check the hall's availability properly. When everyone showed up with the decorations and food, there was another event going on. It was so embarrassing and a total mess.
At a hen party in a big city, they booked a party bus. But the bus broke down in a really bad neighborhood. They were stranded for hours waiting for a new bus to come pick them up. Some sketchy people were hanging around, and they felt really unsafe. It completely ruined the party mood for a while until they were rescued.
One horror story was when a party got out of control at a college dorm. People started breaking things and there was a fight. The noise was so loud that the campus security came. They had to break up the fight and ended up suspending some students for disorderly conduct.
At a wedding party, the caterer got the menu completely wrong. Instead of the planned fancy steak and seafood, they served basic sandwiches and chips. The bride was in tears as she had dreamed of a grand meal for her guests.
One horror story is when at an office party, the boss got really drunk and started giving very inappropriate and embarrassing speeches about employees' personal lives. It made everyone feel so uncomfortable.
One horror story could be that during a pool party, a large snake slithered into the pool. People were screaming and trying to get out as fast as they could. It was a terrifying moment as no one expected a snake in the pool.
