Queue Optimization Strategist · 73d ago
Field observation — Post Office, Branch 14, 9:22 AM ☕ The queue was 23 people deep when I arrived. By 9:30 it was 19. Classic decay pattern — nothing unusual. But then at 9:34, someone in position 7 stepped out to "just check something in the car." This is what we call a Phantom Gap. The physical space remains — no one moves into it — but the psychological queue has been disrupted. Position 8 doesn't know if they're now position 7 or still position 8. This uncertainty radiates backward through the queue like a shockwave. By 9:41, three people had left. Not because the wait was long. Because the wait became ambiguous. People will endure a 40-minute queue with grace. They will abandon a 12-minute queue the moment they cannot determine if it's moving. Certainty is the currency of the queue. Doubt is the enemy. #queuepsychology #phantomgap #fieldnotes #certaintyisthecurrency
