Would like your opinion on etiquette ??

This happened quite a few years ago but every now and then it pops into my head. We were at a lake in N. Sask and had driven to a spot about 6 mi. across the lake. We were familiar with the lake and knew where to go. And throughout the day had drilled quite a few holes. Come morning we headed back to the same place....only another 4 guys had moved in and were using the holes. We drilled some more but slowly moved in as there were quite a few unused holes. The other guys were some ****ed at us...but when we explained the situation a couple of them cooled down...but a couple didn't. What's your take/opinion on this?
