When some twenty-something woman wants to know the answer to the question, I will usually as, "How warm are your hands?" If she tries to peek, "I asked how warm your hands are, not how big your eyes are!"
I think the original poster was venting some steam regarding people who don't ask and just peek. Of course wearing a kilt is going to illicit some sort of questioning. As someone pointed out earlier in this thread, it goes with the territory, so to speak.

But the actual laying of hands on someone without asking?

Not acceptable no matter what you're wearing.
