The "wait until the next day" part. My buddy Jake did that once. He finished his shift, went home, couldn't sleep. Kept staring at the ceiling thinking about the layout. Came back at 6am before anyone else showed up. Moved a whole gondola and three endcaps by himself. Took him like two hours. Said his back hurt for a week but the flow was way better.

Honestly I just toss mine in with everything else and haven't had issues.

30 bucks says the blade gap is too small and it's pinching the hair instead of cutting it. Did you try running it on a detached blade first to see if it sounds different?

Respectfully gotta push back on the broccoli thing. I throw broccoli stems in my bag every week and never get bitterness, but I peel the tough outer layer off first. That green skin is what makes it gross. Also timing matters a lot - if you boil it for more than an hour the brassica family stuff starts turning funky. I do 45 minutes tops when broccoli or cauliflower scraps are in the mix. Carrot peels and celery tops are safe no matter what but I bet your buddy left the skin on and let it go too long.

Oh man, folding the seam back to double check is a lifesaver on busy patterns.
