I had that happen on Hickory when I was trolling for stripers. Went over a spot a few times and picked up one every time. Another boat pulled up and anchored on the spot to fish with live bait after watching me. I went right down my original path within a foot of their boat and they had to reel in all the rods on that side. They started fussing and I just laughed and said I was here first and circled around to make another pass. They pulled up and moved.
