Of course, being in public, there's no expectation of privacy, and simply wearing a kilt means you'll draw more attention than someone wearing jeans and a t-shirt, AND that same person can simply take your picture anyway and there's nothing you can do about it. But there is a difference to me appearing in a clandestine pic and a posed one. Sometimes I'm not in the mood to stand and smile or pose in any other way for someone else, and wearing a kilt shouldn't force a change in that.
Very true. It's almost like being a celebrity in many ways. No matter what they do, the paparazzi is going to be there taking pictures, and there's nothing they can do about it. They can either choose to constantly run and hide and live in torment, or embrace it by posing and being friendly with the paparazzi. Wearing a kilt produces much the same effect, though to a smaller degree.

It's certainly understandable not to want to pose and smile for every goofball with a camera; that will get old real quick. Maybe we should get some suggestions from the rabble for 'canned answers' as a way to politely say no to such requests?

I know a guy who travels all over the country selling leatherwork. He's very eccentric (he wears a top hat!), and people are always asking him if they can take his picture. He started charging $5 per picture. Apparently it's a pretty lucrative thing, because he's raking in some decent money from it!
