Not "bad form..." You're in the U.S. From comments here online, t's apparent to me that nobody there knows or cares. In the U.K. they'd possibly think you were weird & perhaps thoughtless. In Canada, folks either wouldn't know, or if they did, they'd just roll their eyes and snicker to themselves.

The question then, becomes not whether others care, but do you care about them?

Bad form? Etiquette? Consideration? Thoughtfulness? Your call; which of those is important to you?

For example, in my own case, I have clergy & hunting Sinclair. Tomorrow I'm being measured for a Sinclair modern. I'm a priest with Sinclair heritage, so I'm connected to all three. Nobody here asks much, but were I travelling to the U.K. I'd only take one lest people thought oddly of me.

Here's the thing: nobody would ever say anything but I for one care about what others think even more than what they say, after all, if they say something to me, I have a chance to explain it. When they say nothing, they leave with heaven knows what opinion of me, and yes, I do care what opinions folks have of me or if they're offended.

Do you care?
