I would let my opponent borrow pretty much anything except my playing cue. I have let someone borrow my spare cue before. Chalk, bridge are all no brainers.
That being said, there are a few people I know to which I wouldn't give the sweat out of my buttcrack if they where dying of thirst (sorry about the graphic image I just planted in your head).
Here I am taking an afternoon tea break, eating a delightful tuna sandwich and catching up on the latest on AZ, and it's all ruined by the dirty image of a sweaty man's buttcrack. Thanks buddy!
