Usually I show them how far my forklift can place their freight without scooting it (which is never far enough (only when they complain about the potential for scratches)) then mention, "Unfortunately without scooting it you'll have to load this by hand."
Usually this gets them to relent and then I get to show them how tough the lining is by scooting the freight and not damaging anything
Sometimes though they still don't want it scooted so they end up having to load it by hand by themselves (I can't help by hand as it's a liability thing) which always brings a smile to my face
Literally today some dingus ended up loading 5000lbs of flooring into their F-550 by hand because they didn't want the rhino lined bed scratched
The hell...I have a pickup with bedliner that we use (in part) for picking up pellets for our pellet stove by the ton. They put the pallet on as far as they can while it's fully on the forks, then lift up the end of it and push the pallet on to the truck the rest of the way. No issues at all, and we've been doing it for several years now.
I throw all kinds of crap on it. A few years ago we were getting rid of fencing the previous owners had left...the only thing I had to worry about was them tangling enough that I wouldn't be able to get another piece in (we have a cap on our truck). That's the whole point in getting the bedliner. I'd refuse to help someone doing that.
One day my friend told me not to grab any tools on the way to a junkyard, as they had everything we would need already loaded.
Later on, they didn't want me using said tools because they were new and might get scratched or the ratchet gears damaged. Kinda wanted to punch him in his idiot mouth.
I treat my tools well and even baby the fancy ones a bit. But god damn, they're fking tools, they're meant to be used and eventually everything breaks.
A friend's somewhat classic car has a tire change kit and we get a flat tire, they don't want to have the change kit show any wear, so we end up waiting hours for roadside assistance to come change a tire... not with the included tire though.
