I usually like to go to the movies on Saturday nights since there's a nice theater that's within walking distance from my house. The staff is really nice and I've never had any unpleasant encounters there. So I get to my seat before the movie begins and after a few seconds I notice that the guy sitting down the row from me takes a picture of me on his phone (with the flash on!! he didn't even try to be subtle about it!) I was naturally very upset, but this has never happened to me before so I didn't even know how I should react and I didn't want to make a scene so I just let it go since this happened moments before the movie started. I have a feeling this won't be the last time something like this is going to happen, what should I do or say when it does? How do you handle situations like these?
