My old boss had a similar rule for tape backups.

Watched our main espresso machine give up its ghost right before a Saturday morning wedding rush. We had two little home machines we use for staff coffee, so we lined them up on the bar like a sad, slow firing squad. Took about twenty minutes per drink, and I'm pretty sure we killed the goodwill of everyone who ordered a latte.

Your elevator shaking issue is why I stopped skipping cleanings. I used to think it was just busy work, but now I know it prevents callbacks.

Waste less time arguing honestly, most conspiracies are just WEIRD hobbies people get too into. @blake_lewis has it right just letting folks talk until they hear how silly it sounds.

Oh, I dealt with this exact thing! I tried silicone spray on the seals for years and it only helped a little. The real fix for me was the wooden door frame itself. All that humidity makes the old wood swell up just enough to press against the door. I ended up taking a plane to shave a tiny bit off the top of the frame where it meets the door. No more sticking, even in a storm. Maybe check if the door is touching the frame when it sticks.
