I guess these things matter a lot to many people. Ten minutes here or there can be a massive inconvenience.

I'm on the red-eye out of JER on Thursday, ETD 0700. Taxi is booked for 0530, should be there by 0550 ... drop a bag and grab a last cigarette [for some 15 hours]. Security around 0600, Galleries' coffee and .... breathe.

I'm enormously grateful my life doesn't depend on "10 minute windows", and I do genuinely have sympathy for those whose lives seem to be driven that way.
