I did last night. This is him, right before leaving sticky fingerprints on the front element and all over the lens hood of my 10-22mm.
I know I overreacted, but I read him the riot act. I feel a bit bad, I probably should have apologized once I calmed down, but he looked to have moved on from the incident which, in all reality, was an incident for me but an "oops, sorry" to him.
But this is the first time in 14 years of photography that I've ever done this and that includes a 5 year stint in Photojournalism.
So, it made me wonder, has anyone else given a subject a piece of their mind? Or worse? And what for?
