Only rational if you’re the last person in line and not moving doesn’t spill people out of the designated waiting ropes.
Its only the same if you strictly consider ‘the time I stand in this line’.
Its different because everyone behind her loses a feeling of progress from moving up, and it increases the queue length (at least visually) which can impact other people’s decision on which queue to join which, of course can impact the other queues.
To think the way the image suggests is to be inconsiderate to others around you.
losing a feeling of progress
Right, that’s why it says perfectly rationally. If someone is really being perfectly rational they should only care about how long they wait inine, not a feeling of how long they wait. I don’t think being “perfectly rational” is something folks should strive to do.
Fuck everyone else though right? That doesn’t sound rational does it? In that case why even wait in the line? Just walk to the front because that will shorten your time
