Did you ever think about how much water you're wasting by running a whole extra spin cycle just to save a buck? Every quarter you save comes out of the same pocket eventually, since the machines are built to make money no matter how you load them. The real trick is going when it's dead quiet and asking the owner if he'll cut you a break on a slow day.

Who's gonna tell them what aging actually means?

Honestly I did the exact same thing last month and ended up ripping the page out entirely, which just made it worse cause now the notebook has a gap. I keep a little pencil case with just my layout pencils and a white eraser now and it has saved me so many times. The taped square thing is real though, you are not overthinking it at all.
