That happens with any book or movie about a place. Reality never matches the polished version someone writes about.

My own tech is so old I tried to explain the grandfather paradox using a busted overhead projector. Had to draw the timeline on a napkin when the transparency jammed. Pretty sure I accidentally argued for a version where you just make the projector disappear.

Training staff to trust their senses with daily checks could prevent a lot of good food from getting tossed. It comes down to having a crew that's alert and can make smart calls on the spot. Dates are useful, but they shouldn't override common sense when something still looks and smells okay.

No kidding, it turns a good polish job into a gummy mess. My own lack of patience probably doesn't help, but that's the whole point of a quick dry, right? I'll sit there waving my hands around like an idiot, only to have every cat hair in the county stuck to my nails. Kind of defeats the purpose if you have to wipe it again anyway.

Ever put a cheap comb in barbicide and seen it warp? I had some combs turn cloudy and brittle, but my good acetate ones stayed fine. The softer plastics seem to soak up the solution and get messed up faster. So yeah, the type definitely matters from what I've seen.
