My grandma's old kimchi fridge from the 90s was a total mold trap after she stopped using it. The rubber seal got all cracked and brittle, it smelled weird, and it just held moisture. That manager got lucky. Most of those old fridges are not airtight anymore, they're just bulky and inefficient. You're better off with a new, clean food grade bucket with a gamma seal lid. Why trust a 15 year old seal with your dry goods?

But honestly, sometimes that blunt feedback is just wrong... like @ryan_smith37 said, a quarter inch seems way too deep, you'd deflate the loaf. Some customers just have a personal taste thing, not a real flaw. I had a guy tell me my bagels were too chewy... that's the whole point. You can't please everyone, and changing your process for one opinion might just make things worse for everyone else who liked it before.

Wild setup" feels like a stretch for a mug, @bailey.xena. It's just a custom shape, not a car part. People get way too into small stuff sometimes.

Oh man, that's the worst kind. Don't feel bad about the time spent, a single rock can create a perfect seal. I once tore apart a whole sprinkler zone for a tiny piece of root that looked just like a drip emitter.

Wait, is this grid line vs area debate even a real problem, @danieljenkins?
