I haven't had a close call with a submarine but the goddamn glass bottom boats full of tourists would come and just hover over us while we were working in Curacao and it pissed us off to no end. For one thing it's a safety issue, but for another thing we don't want tourists seeing us catch fish for research and think it's okay for them to do the same. The methods we use (barrier nets, dip nets, and chemicals while on SCUBA) are straight up illegal for anyone who doesn't have special permission. We're also often negatively buoyant and crawling around on the substrate, so it's not even a good example to set for the tourists for how to dive safely/responsibly.

Also possibly the most terrifying "I'm going to loving die" moment I've ever had on SCUBA was when one of those fuckers went right over us in barely enough water for us to cling to the bottom and have it go over us. I could feel my whole body thrumming with the vibrations from the engine.
