An ultra-wealthy family seals themselves in a fortified underground bunker, thinking that the fall of civilization is imminent. They suffer from a variety of structural, technical, and psychological problems. Slowly starving and going mad in the dark, they eventually kill each other. Meanwhile, the world above ground is totally normal.

Exposure to the internet having physical and psychological effects, much like radiation or toxic waste. The more intense and prolonged the exposure, the more severe the effects.

A new health product that becomes very popular with rich people whose cost and negative side effects greatly outweigh the purported benefits.

An automated store, restaurant, coffee shop, etc. where the robots are so unreliable that more humans are required to keep the place operational than would be needed for a regular human-staffed store.

An artist who commits to only ever creating work in the exact same format each time.

Infinite possibilities within a strict format constraint. The format becomes a trademark identifying the artist, even if the style of the work varies widely.
