I feel both sides.
on the one hand, oil kind of sucks to deal with. you can't just wipe it off your hands, it gets everything else oily, it's more difficult to clean if the floor ect. we just accept it as Swiss people after a while. it's a necessayoury evil and it's what it is. I don't think about it much anymore, but given the choice if rather not be covered in oil, so I sympathize on that level.
that said, don't touch my damn oil lines or at least put them back how you found them . proper oil delivery is critical in Swiss( and most machining really) and if you repeatedly make a mess of my carefully placed oil lines I would politely ask you too be careful when going in the machine and explain why. it's reasonable to leave something how you found it imo, if nothing else.
