One time at BCA nationals in Vegas I sat down right in the line of a lower-level Euro pro player on the outer tables about to take a long straight-in shot. I was looking at another table and didn't notice that he was shooting. I froze and tried to minimize the damage, but he didn't stop his routine and he missed. It was a critical point in the match and he ended up losing. I felt bad, but there was no shot clock and nothing was stopping him from regrouping. Those outer tables can be kind of a zoo with people walking around and talking. Perhaps a lesson learned for both of us.
