Really depends upon the club and rules that it goes by.
Many clubs go on a first come, first served basis to minimize issues like this.

Others allow for "ownership" of stands not located within 100 yards of a green field and all green fields are first come, first served. This seems to be the most reasonable approach. If your club allows private green fields, or corn feeders, then the second guy absoloutly broke trust. If it was a club field or area, then what did he do wrong?

Really isn't enuff info here to really hang the guy. But, he certainly didn't make any friends.
