I don't get involved unless i'm cleaning for them.
I learnt that when iceland went national years ago and the manager asked me to provide him with a scraper and he paid me out of petty cash, for which we both signed.
2 weeks later i see him with his arm in a pot-severed the tendons in his thumb using the scraper and needed 3 opps to sort it out, felt really sorry for the guy as he was doing what he thought best for the company :

Then the b*****d (prompted by the company) tried to claim of me for injuries due to me not training him to use it
