Gotta agree with several comments here - these folk don't consider those terms offensive. In fact, they don't do the 'verbal repartee' thing - if youv'e p*ssed them off they won't swear at you, they'll clean your clock - usually with a dozen or so of the 'lations as well.

The pad had lights installed on towers, as well as in-ground illum of the pad and the walkway leading to it from the hospital. The lighting lasted less than a month before every one of the ground lights and tower lights was smashed. You just gotta shake your head......
