Do you find that people make you stingy?

Do you find people make you stingy? You try to be a good Joe and help out people by letting them borrow your tools etc or giving them rides but they break or lose your stuff and sometimes just rip you off or, want all sorts of side trips but never offer to replace any of the gas? Then you are the one doing without or having to spend extra money on things you would not have if you would have been anal about it and told them to go get their own gear because even though you were not using it at the time you did not want to risk it getting lost.
