The whole whole taking pictures at every gathering pisses me off to the point where I refuse to pose for the picture. I know full well that no one will ever look at it again, so why am I going to spend my evening getting time trolled for 20 pictures during the evening?
It caused some arguments when I first deployed this approach, but now other people are deploying it, as they see that if you allow this to continue, all the picture taking adds up to a lot of time / inconvenience for zero return.
