List of things that annoy an optimizer (not remotely comprehensive)
Boarding airplanes.
People blocking aisles while boarding when 200+ people are waiting to board
Flight attendants not encouraging people to clear aisles and speed boarding.
Flight attendants slowing everyone handing off candy while the whole plane is boarding in the rain and people are queueing on the stairs.
Water heaters around the world, reheating the water just after everyone else showered at home. Only to be wasted in the next 12 hours overnight.
Sprinklers running on “schedule” on rainy days
. Teas not served in a way you can remove the tea from the hot water on second serving.
