That paper trick works every single time for me too.

Actually, a slow cooker uses way more power than people think, especially on those long cooks. My electric bill spiked a bit when I first got mine. The real saving is from not buying takeout, which is way more expensive than a bit of extra power.

Honestly, that's a solid wake-up call. When you're grinding through a busy day, where do you feel the rush shows up the most? Is it the pressure to finish the outline first, or do you find yourself getting sloppy with the clipper-over-comb work when you're behind?

Bent pins are the worst kind of time sink.

That "good enough for now" line is a major red flag. I'd just ask directly if they have a plan to install proper ventilation soon.
