Scarcity can make a limited resource feel more valuable or urgent. A limitation matters most when its cause is clear, such as genuine stock or available seats.
In the demo, a booking changes both the seat grid and remaining count. The important mechanism is that the message reflects actual availability rather than an arbitrary countdown.
Avoid fabricated counts and timers that reset without cause. Show cancellation terms and restock possibilities when they matter to the decision.
When to use
Show availability only when seats or stock are genuinely constrained.
