Kelly,
Do you pee on the greens? Do you pee knowing that your playing partners are watching? Would you do so if you knew the cameras were rolling?
I suspect the answers to these questions are all no, since I don't recall having noticed you spit or pee when I enjoyed playing with you at Muirfield. FWIW I also pee on the course (well, off to the side, discretely (I hope) hidden in shrubbery, mostly), as, I suspect, do a majority of GCAers. I've certainly been aware of other GCAers disapperaing for a pee. I'm yet to see one spit but that doesn't mean they don't, just that they are discrete and do it somewhere it won't be obvious and nor will the aftermath.
