No way @richard_mason, you actually revisit bookmarks?!

Saving glass jars from pasta sauce and pickles. My whole cabinet is full of them now for storing leftovers and bulk food. Beats buying new containers every time.

See, that's what my friend thought too, until her car was stuck at the shop for a full day because of an update. She went in for a simple tire rotation, but they said a major software patch had to install right then. It was exactly like @violao10 said, the car needed to be parked and off, so they couldn't just do it later. They didn't have any loaners free, so she had to wait around for hours. All that smart scheduling talk means nothing if the shop doesn't actually plan ahead. Now she has to take another day off work to finish the update.

Ah yes, the classic "cheapest fix" where concrete becomes the city's answer to everything.

Patterns can be tricky though. My old bus route had a Tuesday delay everyone blamed on garbage trucks, but the schedule data showed it was actually extra traffic from the early shift change at the factory. The street sweeper might be part of it, but there could be another clog in the detour route itself. Sometimes we fixate on the first answer we find.
