Way up in a small town I offered to check the oil in a lady's LOUDLY clattering gas engine.
I pulled the dipstick and it broke off level with the top of the tube. The tube was solid with rust as well as the dipstick.
I said clearly, "This engine has been severely neglected. The clattering you hear is not good. If you have no mechanic to perform an oil change, ask your friends for the name of one."
Then I swore to myself NEVER to make such an offer again. It could've gone real "small town stupid".
