One of the guys I play with regularly told us that we should never stand against tee markers or signs because men often use them as urinals. I've played with guys who will walk over to a bush - just in case anyone is wondering - most women are disgusted by this behavior on the course - a little discretion would be nice - but to find out that standing on the tee isn't safe bothers me. We had an add-on guy with us who went standing right in front of us on the 4th hole - we didn't talk to him much after that. Do you ever consider that your ball might end up landing where the guy in front of you went? Does this not bother anyone at all?
